Weird.
I can heal and DPS perfectly fine using a controller. Haven't done Coil yet (attempt tonight hopefully), but killed Titan a couple times as a DRG and doing some good speed-runs in WP which are quite stressful for my undergeared healer (I use <tt> macros for healing BTW; makes things easier. Select tank, heal as normal, <tt> your offensive spells and you don't have to worry about attacking an unclaimed enemy. D-pad to select other party members; just remember to organize your list right), especially when your PAL decides to pull 4 groups at once...
I only just got WAR today, but switching targets isn't bad in dungeons at all yet.
Swapping hotbars takes maybe half a second, and once muscle memory kicks in its just a quick flip to use some CDs or secondary skills. As long as you know where your buttons are, its not bad at all. But that applies to KBM as well...
