Hmm not too sure about the mouse thing?? It should work right the way you describe it.
Yeah Hybrids, Ranger included, have a 40% penalty and some, Troll, Iksar have even more added up to 28%. Ranger truthfully is not the most wanted class on here, but I think that will change a bit when Velious comes out. Their Tracking ability will be needed, and they will be able to solo better, and the Hybrid penalty will drop hopefully after a couple of months into it.
