Versatility might be a trap. It's funny, because when I first saw it I thought it was OP, especially with the likely option of juicing it via specialization points. But now that I've thought about it for a while, I'm not sure I'll ever try it. Having attack points that aren't backed up by feats isn't all that appealing.
It might be a good choice for newbies who haven't figured out the systems yet, letting them try lots of things without having to actually spread themselves thin on skill points. Probably not that many newbies trickling in at this point, although I still hope to convince my brother to give it a proper try one of these days.
I might ever take Versatility on a melee character to give myself backup ranged options. To me this feels like the most advantageous use of Versatility. But more likely I'll just keep putting a few points in Throwing and chucking grenades. (Looking forward to a sword and board character once the expansion lands.)
