There's a difference between barbarians without a brain and barbarians who just use a brainless build

I hate both, but there isn't a real chance to win against a really skilled barbarian who uses such a build and knows how to use it exactly.
But the today's problem is: Skills are hardly needed to play successful. Really annoying...
Thus I'd love to diminish the popularity of barbarians by making them more difficult to play.
=> Less damage per normal hit => more damage by using spells/debuffs/more creative buffs/nice movements (eg: spear does little more damage, if you use the range eg: range >1.7 = +10% damage; no moving increases the defence ...)
Especially movement isn't as important as it should be. Concerning movements, you could have quite a lot possibilities to play.
