I think I have same problem (even though I'm in my 40s, not 60s). Started playing GW1 when I was 30, and it was cool and fun, GvG, some hardcore... But then I found out that I just couldn't catch up with game dynamic, especially in GW2, when movement became much more important. Probably I'm slow and lazy, I don't know.So I got gaming mouse (pretty cheap A4Tech J90) with many buttons -- I use it for healing, targeting, elite, mount, run, weapon skill 1 autoattack, dodge, jump. It doesn't make me pro gamer, but helps a lot -- sometimes I run through regular PvE content barely touching keyboard.
