Cold Snap on Gamepad feels so clunky and bad

It really needs an auto-aim mechanic (similar to D4's corpse explosion) where it will only target frozen enemies.

The issue I run into is in groups of mobs it is impossible to target them if one of the mobs behind the front line of mobs gets frozen.

(x = frozen mob, o = non-frozen mob, p = player)

o x x
o o o

^
|
p

If a player tries to cold snap the frozen mob in row 1, it's going to target the mob in row 2 in the middle and nothing is going to happen (due to not being able to cold snap an unfrozen enemy, obviously) and it generally just feels like a ass.
