the problem I have with keybinds is that I rebind virtually all the keys - then on making an alt I have to do it all over again

Can't we have the keybinds carry over to alt also??

and I use Razer Hex also - perfect for this game

skills 1-5 on mouse

jump is the mouse button 6 and ultimate is Num 0 as I am old school and still use cursor keys for movement.

yeah I mean if you are planning on playing the game for awhile and are into MMOs a gaming mouse and other peripherals like a game pad or gaming KB is a smart investment. Most or at least lots of MMO players have them already so its not really an issue.
