So.. why isn't anyone using E. Arrow - Lightning Bolts? I mean.. it's a guaranteed 1.5sec stun if you crit.. considering the fact that people have high Crit Chance..
Point is.. Thunder Ball + Lightning Bolts, wouldn't that really stun lock monsters?
Sure you'd have reduced damage output because of it but.. wouldn't it help more if you can just keep that enemy in place while others wail at something else? :)
