I fully endorse adding "Implied targeting." I have to admit I was very excited when they said target of target was coming and was seriously disappointed when I logged in for first time after patch. As a healer I have to say the changes they did was pretty much useless.
I get by the with current targeting system just fine, but I think most healers will agree with me that it is largely frustrating. I have my "set target of target" hotkey set to Q for easy access. So on fights like say Bonethrasher, in Karagga's Palace, where he is constantly changing targets I have to constantly hit the hotkey multiple times in order to get on the next target hes about to hit in order to pre-heal him . This works fine until adds start coming out then its a PITA to get back on bonethrasher because DPS is on the adds now and I end up targeting the "target" of the adds which is annoying.
To make our lives more sain I'd love to either see:
Basic Macro's like /target Bonethrasher (so that we can use one hotkey to target bonethrasher then use my target of target to find out who he is hitting.) or you could have /target PlayerName hotkey'd for a makeshift MA. Allow us to target boss directly and since we can't heal the boss automatically heal his target instead of ourself (unless he is targeting me) aka indirect targeting.
Please, please, please, please, please Bioware consider adding one of these two in.
