You can change those but I believe someone already mention something about that. You can change and nerf them but other skills/spells will just simply replace them.

Because the next will be Hexer/DH with first turn CC or LB/DH with first turn CRIPPLING cc or some more crazy ideas like that.

There isn't a reason to change those, just allow others to position themselves in pvp group fights. At certain sections on the map. Ofc keeping the tile distance, just letting them not stand next to each other and within the rush down tactics way.
