I don't know if anyone else finds this annoying or not, but its a real pain in hectic pvp or fleet actions where I'm working a target ( enemy) and need a quick heal, EPS transfer, etc... and cast it and it goes to the target of whom I'm SHOOTING instead of me and not only do I not get my needed buff/heal but I also stop dealing damage in a most critical situation.
If I want to heal/buff an ally, let me choose...do not force it upon me. I do not see an option for this in controls either unless I am misreading something.
Tap escape, tap power, retarget, done in 1 second.
Personally I love being able to hit target of target. It means that, if me and my friend are both hitting a single target and it's locked onto him I can buff him, then when it locks onto me I get buffed.
Making it an option would be nice ("Abilities assist"?) but don't take it away entirely.
