Okay, but some questions first:
Will this be your first Kheldian?
What other archetypes do you favor?
What would you like to do with your new solo Kheld? For example, are you the kind of alien who wades into a group of baddies like a swat van into a riot, or are you the kind of alien who appears in the middle and shreds everything in a 360 degree arc and bites off their li'l heads?
The more we know up front, the less stops there are on the bus to what you want.

This is a fairly complex AT, with different build variants (Tri-Form, Human-Only, Human/Nova, Human/Dwarf to name a few with many shades of gray in between).
Therefore, I'd very strongly encourage you to try out a PB and WS and play around with them to get a feel for what you like, what you hate, and what you want. Also, I suggest you read several of the guides and consider the primary question - whether or not you wish to use forms.
Lastly, I would advise you not to simply pick up a build from the forums and copy it. This AT is extremely flexibile and there is a lot of variation even within the same variant from one player to another based on preferred playstyle and build goals. Therefore, playing someone else's build is almost never as good as playing one you've come up with yourself. We're always happy to help you fine-tune such a build, but trust me when I say that you'll like the Kheld more and be more effective on it if it's your build.

Thanks for the feedback, I am wanting to do a Human/Nova or Human/Dwarf, some thing fast, most of time I play blasters or controllers
I would echo Justaris's words and suggest trying several styles, it's the one AT that plays so very differently depending on the build you have.
My first/second Kheld was a Tri-Form WS, she was pretty amazing and gave me a true sense of uberness. That's no kidding either, squid form is fantastic now and the damage you can churn out is quite scary. You then drop into dwarf form for voids/quants or anything too tough and duke it out with them. You then finally have human form for the buffs and a couple of minor controls. I don't think I've felt quite so powerful on any toon, but, even with all the uberness I stopped playing her. For me, and this is a personal thing, the constant form changing became irritating.
My third Kheld is a human-only PB, and I love her to bits. Though her blasts are weaker than the tri-form, she has great survivability, what with the shields and heals and of course her mighty incandescent strike. Her only weakness is mezzes and I nice dwarf form loads because of it. But, I'm going to remain stubborn and stick to human-only.
The main difference I've found with them is, WS is better at AoE damage and PB is better at ST damage. If you plan to mostly PvE then I highly recommend the WS, if you plan to foray into PvP in anyway then I would recommend the PB.
A lot of what makes WS so great, they don't get until the late 20's and 30's, so if you were tempted by human-only WS then it's a very long haul to get there. So, I would recommend Tri-Form no matter what, at least until you get eclipse. Even if you want to go Human/Nova only, it's worth taking dwarf form just for breaking mezzes or some dr for when you get in trouble.
One of the problems with suggesting builds is how so many powers become redundant depending what you choose. If you go with Nova, then you don't want to take the human-form blasts, they are very weak compared to Nova. You also don't really need the shields if going with dwarf form.
Levels 6-20 have never been so easy or quick on any toon, than with squid form. At level 6 you suddenly have 2 long range blasts and 2 aoes, all of which churn our great damage and you also get some kb thrown in for fun too, plus you're fast moving and airborne. Highly recommended and you can always respec out of it later.
I want to make a new main WS or PB to solo to lv50, any suggestion or favorite builds, thanks
