The game has basically become far too easy and speedy for such tactics to be necessary. I can’t speak for lowbie content, but, in the endgame, if immobilizes are slowing you down... it’s not the immobilize’s fault. Every level 50 team should be shredding 54 mobs like they’re nothing, even if one particular player isn’t able to hit every baddie with his AoE’s.
If someone complains about controls on a level 50 team, best thing to do is look at all the enemy bodies that just instantaneously fell dead and shrug.
