wasd for moving
f for activating fly powers
1-2-3-4-5-6 primary powers, then I bind rest of them because my finger isn't long enough to touch 7-8-9 numbers
shift+1-2-3-4-5-6 for toggle powers, i didn't bother binding rest because they are usually toggle
ctrl+1-2-3-4-5-6 for epic/power pool powers, I bound them to rest of keys as well for ease of use. If power is good enough it can replace my one of primary shortcuts.
shift+g for ohsh*t button, I remember this because i call it godmode and g key for remembering better.
shift+h for summoning umbra beast, again i remember this because that thing howls too much, so h key it is.
ctrl+space for teleporting powers, i usually use maxdistance for this so traveling became easier.
and so on so on, oh AND R key and shift+r key for various recovery powers, for remembering better.
