There are more than a few problems with open mode, like the limited prime hunting spots for mobs, but the biggest one for me is the synchronizing. Unless I am the first person into the scene, the creatures attacks/damage output is out of sync with the animations they make. This makes it very tough, if not impossible for me to dodge the attacks that can be. IE: tail swipes, troll stomps, etc. I have tried different setting modes and none seem to make any difference. For this simple reason, I generally stay in party mode which is a shame.
