Actually, I'd like some kind of option similar to choosing between the big artsy (sometimes unreadable) job gauge and the simplified version. Then you'd tick that option if you want the compressed display of combos (based on pvp but not necessarily the same), or ignore it if you prefer the 1 - 2 - 3 (-4) buttons display.
I guess it would still need some refinements, as some combos are not always so linear but I guess this could help.
