Not everyone has or wants some gigantic mouse with 15 thumb buttons, or mucks with the keybinds. More options are better. I'd prefer a brief time delay on mouseover, even just 1 second rather than disabling skill tips in combat entirely. I have a regular keyboard and mouse. It's really not hard to learn, just takes time to adjust. Don't be stubborn, you're only hurting yourself by refusing to change - seriously, just force yourself to use keybinds. It'll be difficult and confusing at first, but your muscle memory will eventually develop to be able to do it without looking and you'll never need to go back to clicking in any MMO ever again. I use 1 2 3 4 5 for the weapon skills, then Shift 1 2 3 4 5 for the F skills, then Shift Q E F T for the utility skills.
