Well, thought I'd test the waters in the general discussion board (and so far seems so good...?):
Perhaps there could be a buff/redesign for Apprentice DSTs and Huntress ESTs? From personal tests I find that ESTs on NM have a scant higher amount of damage to deal to a single target, whilst costing the same amount of DU as a PMT. As for DSTs... though their ability to shoot through walls is still pretty neat, their poor DPS scaling and high DU cost makes them really quite the difficult turret to actually fit them into anything but a niche build
On a different note - Liked what was done with strength drain auras
P.S. I suppose the same could be said of the squire's spinning blockade, though what can be done about that... meh?
EDIT: Perhaps allowing them to 'mini-stun/interrrupt' targets but otherwise maintaining their current stats? Or would that be too OP? :P
