I also have noticed the respawn rate is unbalanced. We are lead to believe movement is the key to fighting in this game, especially if you are an Elementalist like myself. Kiting usually takes up the last third of the the fight against normal mobs and invariably the odd second mob can be pulled if careless. I would go as far as saying it ‘looks’ like a bug when the same mob respawns from where you have just pulled him from while you are still fighting it !! Please either; up my damage, double the length of my stuns and slows or make it so the area you are in has a suitable respawn rate for the number of players directly around you. I suspect the respawn rate is calculated ‘map-wide’ for the amount of players.
I also agree with the above post regarding the tab targeting system, I too, have introduced non aggressive mobs into a fight by trying to change target between the two mobs directly in front of my toon, with auto-fire on of course, only to launch a single fireball at a poor unsuspecting creature. It’s usually at that point I hear Graham Chapmans voice from Holy Grail shout ‘Run Away’.
