I think the biggest adjustment I'm having to make going back to MWLL from MWO is the torso rotation speed. MWLL is so slow by comparison it's completely thrown me off. I got into my beloved Gauss Vulture and couldn't hit a damned thing with it earlier tonight. Alternatively, it could be just because I'm using a considerably cheaper mouse nowadays compared to the gaming logitech (g500?) I had last year.
The CUAC10 Morrigu is fun as fapp, I can't believe I never used it when 0.7 first came out.
