I was looking at making my Peacebringer a melee type using mostly power pool sets. Fighting gives two melee attacks, Leaping gives one attack, Speed gives one attack, plus the other powers in these pool sets are hand for travel and defense. I plan on using White Dwarf a lot as well (no good PB would charge without it). The secondary power set of PB's also give good defense abilities.
I havnt made it to 50 yet but I am interested in being a PB so I will refer to this later. 9 more lvl's to go 
Not really impess with being a worm though so I might not even take the Nova form.
Alright, here's the Guide for building a Scrapper style Peacebringer that I've been promising to write up. This build focuses on using the Human Melee attacks or the PBAoE's that require you to be in melee range. PLEASE NOTE: This build was built to SOLO, please feel free to tweak it, if you Team the majority of the time. However, please also note that since Dwarf form is slotted, you can sub in as the tank for the team (testified by the three TF's and one Respec Trial later where I have ended up tanking a large part of the time do to tanks dropping). There's going to be quite a bit information in here, so I've broken it down into the following sections.
Also, I am not showing Power Picks for 30+ since by then you should have a pretty good idea where you are going to take your character. This is Guide is meant to give a person a fighting chance in the lower levels, and to allow for a person to build a Soloable Kheldian.

There you have it. That is the way I am building my PB, including current slots. As with any build, some powers come down to personal preference. This build does not use HASTEN, however, feel free to sub it in at one of the optional power spots. Your mileage may very, I prefered Stealth for soloing my missions. Please note, this build has started experiencing issue post 30. Aside from staying in perma-Dwarf form, it offers no protection versus Status effects. Please see a revised build below which partially addresses the issue.

This is a secondary build that I am contemplating respecing into do to the prevalence of Status effects in the 30+ game. Please note, nothing can be done about Disorient effects when running solo short of switching to Dwarf form. Also, I did not play this build but based on my previous experience this should be a viable path to build on with Jump Kick providing a nice filler attack in the lower levels and Combat Jumping giving a comparable Defense boost to stealth. While I include Quantum flight for it's fast speed and intangiblity, please note that I am not advocating Phase Tanking, though it is possible to do it with this build. Make your own decision about it.
Tatics:
Everyone has different tatics, of that there is no doubt, however, I'm going to take a minute to indicate what I have found most helpful with THIS specific build. Pulling with Glinting Eye's is very useful when combined with Stealth, if all goes well, you only get about half the group, and not the full group. Very useful when soloing, or even in teams. To deal with Q gunners or Voids, pop an enrage or 2, a luck, and then Stealth + Build Up will let you get in close enough to Alpha-strike them (especially true when you get Incandecent Strike). As you begin to encounter more Mezzer's, use IS on them first, as it will generally hold them, and prevent them from dropping your toggles or switch to Dwarf form and ignore the mezzing. Here are the Macros and Binds that I use.
<font class="small">Code:[/color]<hr /><pre>/bind shift+lbutton "powexec_name Energy Flight$$powexec_name White Dwarf Step"</pre><hr />
<font class="small">Code:[/color]<hr /><pre>/bind shift+lbutton "powexec_name Quantum Flight$$powexec_name White Dwarf Step"</pre><hr /> Please note, the 2nd bind will replace the first once you get to the point where you can use Quantum Flight consistently versus the End Drain.

<font class="small">Code:[/color]<hr /><pre> /macro WD "powexec_toggle_on White Dwarf$$goto_tray 5" </pre><hr />
<font class="small">Code:[/color]<hr /><pre> /macro HF "powexec_toggle_off Bright Nova$$powexec_toggle_off White Dwarf$$goto_tray 1" </pre><hr />
Philosophy:
If you made it to 50, then I really shouldn't have to say this, but 6 slot, 6 slot, and 6 slot your important powers. Some people have indicated that if you use Nova form you can get by without 6 slotting the attacks, I have not used the Nova form, so I can't attest to this. However, with Human/Dwarf you need to 6 slot as much as possible, especially your bread and butter attacks for human form and you Defense for Dwarf form.
One important thing to remember, is that the more Defenders and Tanks on your team, the better damage you deal in Human form. Also, the more Scrappers and Blasters on your team, the more Damage you can take. And last but definitely not least, the more controllers on the team, the harder it is for status effects to take you outa commission.

Quantum Flight - (Level 28) You shift your quantum matrix and become more energy than matter. No long bound by the laws of normal physics, you become intangible to other entities and can fly at high speeds. Quantum Flight grants some stealth, better flight speed then normal Flight, but Endurance Cost is high and since you are intangible, you cannot affect other targets while Quantum Flight is active.

Light Form costs little Endurance to activate, but when it wears off you are left exhausted, and drained of almost all Health and Endurance. Recharge: Very Long
Inherent Powers:
Energy Flight - (Level 1) Fly allows you to travel large distances quickly. Energy Flight is not a good power to use in combat since your accuracy is reduced while this power is active. Your Fly speed increases with your level.
Cosmic Balance - (Level 1) Kheldians naturally thrive off the energy and essence of their Teamates. Peacebringers metamorphic nature allows them to bring balance to their Team. Your Damage Resistance will increases for each nearby Scrapper or Blaster Teammate. Your Damage will increase for each nearby Tanker or Defender Teammate. Finally each nearby Controller Teammate will grant you limited Protection from Sleep, Hold and Disorient effects. You cannot put Enhancements in this power.
Combat Flight - (Level 10) For hovering and aerial combat. This power is much slower than Energy Flight, but provides some defense, offers good air control, costs little Endurance, and has none of the penalties associated with Energy Flight. Switch to this mode when fighting flying foes.
