You don't say what level you are currently or how you prefer to play (tri, nova/human mostly, PvP build etc..). I would say at first glance your slots seem a little off tho...
I'm no expert on the leadership pool but I don't think Tactics will actually make up for not having acc enh in any attack, and it definitely won't whilst in Nova or Dwarf form. The whole leadship pool may be worth a rethink.
Having enough slots being such a problem for Khelds means I've always tried to use them in the most effecient places. Five in Energy Flight for instance? The two end mods in Nova may be better placed as end rec on the Nova AoE instead. I don't think you need an end mod in LF either, especially as you may well be running Conserve Energy at the time. Unless you plan on dying lots, the two slots in Restore Essence might be better placed elsewhere. I would be tempted to try and get Reform Essence in too, the heal is very nice when you need it.
Just my initial thoughts anyway. 
I agree with everything Faultline said. Your accuracy will be very bad with this build and I'd ditch Leadership altogether, toggles are a pain for a triform. if you definitely want to go with Tactics, at least slot it up with 3 tohit buffs. Peacebringers get the second best bonus from Leadership so I think with the -def in attacks the acc might just about be adequate for human form attacks, but you do need accuracy in forms. However I'd take some powers that don't need a lot of slots for instead. Quantum Flight is nice and consider picking up Restore Essence. I know you have a slotted up self heal in Dwarf but you'll want one you can use while in Light Form. Essence Boost is good but it isn't up very often, especially with just one recharge.
Also seems to me that you're wasting slots a bit in places where they aren't strictly necessary. Endurance reduction in Dawn Strike is pretty pointless as it drains all your end anyway. I'd also take the extra slots far away from Hurdle, Health, Restore Essence and Energy Flight. Fly in Nova, it's much cheaper. You'd probably be better off using these slots and the ones spent in Leadership for slotting up your attacks and self heals.
My PB is at lvl 40, and Ive found that I got on fine without bothering with Nova, and, infact, once you 6-slot the two shield powers, Dwarf mode becomes obsolete. I've found that sometimes, with both shields up, I can tank better than when in dwarf form, not to mention my self-heals are stronger/faster in human form anyways. As far as acc. goes, i think I 6-clotted it with acc...not totally sure, at work at mo. Only thing that is a genuine problem with my pb is end. Without RA it goes very quick, but then, during soloing, against 2/3 grp mobs, up to 2 lvls above i think, I can safely remove them without much loss to hp. I havent bothered with Dawn Strike yet, went for Light Form instead, which helps greatly sometimes against bosses/big mobs. Still think a respec might be in order tho hehe. Will try to post my enh when i get home.
My peacebringer is one of my fave. characters. Hes great to play and can really pack a punch when needed. My build atm is not doing so well, after a respec gone wrong. This is my new planned respec build, and i would like to know what you people out there think of it.
