Re: D&D 3.5 Incarnum game?
Hm, normal or Gestalt?
While I will play either, I personally feel that incarnum goes much better with Gestalt. Having another class simultaneous with your incarnum class helps give in-combat options that incarnum sometimes lacks (beyond the ability to quickly and easily change your bonuses). But it isn't a deal breaker if you don't feel comfortable with Gestalt.
Also, as my precision color strike in the community chat thread about incarnum may have revealed, I would like the option to make incarnum more colorful. As in, you can personally choose what color incarnum presents when you shape it instead of being stuck with various shades of blue for the majority of soulmelds.
I would definitely like another chance to play with incarnum, though, any way you feel like running it.
