Sorry, but where has it been said that the developers are striving to emulate D&D? In any case, no... it's not like trying to be a Klingon scientist, because anyone -can- be scientists already. If you want a granok scientist, there's nothing to stop you from making one. The only racial restrictions are the fighting methodologies available. I have to say that the example of a granok spellslinger isn't a particularly compelling one to me because I just don't see them as acrobatic spellcasters/trick marksmen. Same for espers, I don't really see them being big on that kind of magic. Of the four classes released so far, warrior is the only one that really fits with the granok's physiology. As has been said in this thread and elsewhere, they'll more than likely have access to the final two classes. Ergo, their healing option will be provided for and likely the ranged DPS one as well. Meaning there's a very high probability that all of the basic roles (melee DPS, ranged DPS, tank, healer)will be available to them. So the problem here is... what, exactly? That the granok can't go into Wolverine mode when they're already The Thing? That they can't do John Woo gun fu or use fluffy bunny nature magic? Perhaps you can simply enjoy the races that the developers created as they imagined them, instead of jamming square pegs into round holes in an effort to redefine everything in a way that suits you.
