I just started SWTOR the other day, and hit level 10 to pick my specialization. I want to heal, but I noticed the only way to do so is by clicking targets and then casting my spell. I played WoW since day 1, and have always appreciated the mouse-over targeting. Is the pace of damage in SWTOR so predictable/consistent that target-clicking prior to casting isn't really a hindrance? In WoW, you could save a lot of time with mouse-over healing to handle difficult healing phases, so I'm just wondering if SWTOR is just slower paced in regard to group/OPs encounters.
Also, how does target-clicking affect queuing spells?
