Apologies if this has been said before, but the automatic switch on melee to the combo stance results in unwanted character movement. I have now found myself attacking multiple targets only to perform a melee manoeuvre that throws me off the terrain, thus losing built up abilities such as scarab armour, vex armour etc. it also can cause unwanted effects such as Limbo leaving his cataclysm. With quick melee this didn't happen; you retained the ability to stand your ground and slug it out with quick melee.
I appreciate I could remove the stance, but with an associated capacity loss. Perhaps a generic, no combos stance?
