right now minons oly used for dmg and they are pretty weak, dont worth money/skill points.
So what if minions could do some negative effect and the more the bigger the effect,
Some could do slow in each hit and it stucks when some other minions that slow hit, but they will be melee
other can reduce armor
other can be used as buffers for dmg or health or health regen or armor
other can reduce dmg or do a million of other negative effects. That's will maybe make minions worthy. Also a small increase to their speed can be useful since most demiods will try to avoid them
