User blog comment:ShineKuzu/A Cool Arena/Colosseum Trick Few People Know/@comment-30815167-20180813234928/@comment-35742689-20180814042457

the problem with quests is that there isn't a fixed action duration. in  arena/colo, the BB cut-ins actually significantly affect the timing of ur BB/SBB. however, in quest mode, no matter what speed u set the actions will go at the same in-game timing. this is why this trick is mainly for arena/colo.

don't forget to check the animation speeds of ur units when using this trick, always look for the first attacking frame of each unit
