OOC: Kheldian Discussion

Hello Heroes!  Time for a little OOC discussion:
As Arty slowly marches to 50 (4 1/2 bubbles to go as of this writing!) I've begun thinking about rolling up a Kheldian.  My first choice will be a peacebringer tied into the Project Pegasus timeline, but how to build him?

My first thought was to go entirely Human-form and run a blapper with shields.  But that's basically Arty MKV now.  Then I was looking at a pure three form.  Well, that's hard to do out of the box . .  .. Basically you don't get to do anything well for a long time.

SO, I've concluded that playing a Kheld from level 1 will require a designed respec build.  Now the rush to @ level 20 is pretty fast, so I could deal with almost any build for that long, so here's my thought.  I'd play the character as a pure human build until @ lvl 20.  At that point I'd respec into a tri-form build, concentrate on the Nova form to begin with, but slot the Dwarf for Resists ASAP, making it an emergency form and 'in a pinch' tank.  Some time in the 30s I'd spec to a more balanced build between the 2 Kheld forms, shorting the Human form of slots.  By the Mid 40s I'd become a true tri-form, slotting the Human attacks and Dwarf early and taking Nova later in the build (it needs many fewer slots).

So, any comments on this?  What's your experience?  (PS: Oh how I wish the RO forums weren't blocked at work . .. )
