I tried out the melee attack dealio today, with the circle strafe around the mob, it's a little bit iffy. Is everyone's hit box the same? Trying out a few half elfs and making them as small as possible, I would circle strafe a scout type character behind the mob and it would be out of range and not want to auto run back in many times. It felt like there was too much focus to actually get going with it to make it worthwhile, spending that 2-3 seconds felt like an eternity, although in eq2 it does seem like there is a larger room for error where split decision in wow cost you a match.
Perhaps focusing on a more caster based system would be beneficial.
