i've said this before and i'll say it again, if they want the clusterfuckery of rtwp but without actual hotkeys (like RTS type hotkeys) then yes, we'll be pausing every 1.34532 seconds. The hotkey bindings are for bullshit stuff like "options" and shit that isn't occuring during combat, the one place where quick movements matter most. They need to look at dota2 and lol and starcraft and the blizzard games, consider how to make their abilities fit within a hotkey frameset, and then build hotkeys and remappable hotkeys.
abilities should be mapped to q,w,e,r,z,x,c,v with attack being a, scouting or stop being s, d and f also being used.
then they should set up their classes with these sorts of things in mind. too many abilities to hotkey (like the mage)? Easy, you go multiple levels of hotkeys.
Q,W,E,R,Z,X,C,V on a wizard should select the spells from level 1,2,3,4,5,6,7,8 respectively. Then a second window should open with the four spells you are allowed to memorize in your grimoire mapping to q,w,e,r. Other abilities (grimoire bash, etc) can be mapped to other keys.
Same with other classes: fighter type classes can also have the same thing: divide your options again to per-rest, per-encounter, per-day and map those to q,w,e,r, then under the submenu, put your abilities again under q,w,e,r. So carnage which I think would be a per-encounter should be hotkeyed to Q,Q.
