The devs have come out against IWT and from the podcasts it sounds like its not something they're ever going to implement (my opinion) so I wouldnt wait for that. If you are interested in melee you're going to have to do it the old fashioned way.

Im still examining the trees, there are a lot of fun possibilities. Just for funs sake I went with 1 of each archetype and (because im doing 5) the 5th is an additional bard for more buffs.

Spamming 4 of the same type would probably be easier though.
