This is probably low priority, but I tried playing as a ranger this weekend and I wasn't very impressed. The HIPS and heals are nice, but their DPS isn't very good. I seem to recall that long ago a ranger could handle multiple creeps, now I can't take even one without help. Maybe I'm just misremembering.

Also the third ranger slot that unlocks when the whole map is red (quest Taking Back from Angmar) still scales to level 100. I spent a most interesting hour cowering at the back of GV lest a spiderling accidentally glance at me and make me go splat.
