I think the biggest problem in trying to spur on more "innovation" is that we all already have ideas about what "can't be done." And I don't mean things that are technically impossible, like making a bard pally (although I've oddly enough encountered a monk barbarian....) but from my own experiences builds like cleric-rogues and wizard-fighters were said to be impossible. Blah and blah quest can only be completed if we have a rogue/tank/healer etc. When I started playing I just did what everyone told me to - I figured they were right and knew the game better. Even now sometimes I look at a person's build and think to myself "what were they thinking?!"
However then I realize I contradict myself since my current favorite character happens to be a cleric/monk/rogue which I've used to solo Proof is in the Poison on normal and hard at lv5 without using a hireling. With that same character I joined a pug with a "real" rogue and a "real" cleric both of which ended up in my pocket for a ride after the first fight. The "real" dps could barely stay alive chugging tons of pots between fights. A lot of my success comes with knowing the quest but at the same time I wouldn't have been able to do everything necessary to get by being a "real" anything. This build can't heal as much as a full cleric or do traps as well as a full rogue or dps as well as a full monk - there are definitely limitations.
With innovation we realize there are limits, but these same limits are what keeps us from being innovative to begin with. Sometimes you try something and it doesn't work for you, then you tell everyone it can't be done so no one does it. Sometimes you do something amazing and tell everyone... and no one believes you because it can't be done.
Interested to see this monk/barb because monks are required to be Lawful, and barbs are required to be Chaotic. Details on how this is done.
