Wait, how is that a decent reason, though?
Having to follow a rotation doubtless ticks some people off. Yet we don't give it a nullification button. Nor, if an ability had been given by which to prevent the need to optimize one's sequence of weaponskills or spells for a time, would we protect it absolutely just as to "avoid ticking some people off."
A fight mechanic bugged and was therefore far easier than it should be, even if only part of the time or under rarely-known conditions? Nope, can't fix that; it might tick some people off.
