Any end-game healers use a controller?

Want to know how long would it take to switch from top to bottom...Because during coil turn 2, both tank need to pass aggro constantly. And if ur tank not super well geared , 2-3 second delay would kill him.

Really? If you rearrange your party list it is 2-3 taps of the D-pad to target a tank if you aren't targeting anything. If you have both tanks next to each other and are targeting one already you only have to hit D-pad once to switch between the two. I'm sure anyone playing this game and manages to beat titan and get into coil can hit a freaking button once fast enough to do the job, especially since you can switch tanks while you are mid-cast.
