I'm surprised no one's mentioned that you do not always want to move and it is beneficial to stand still for mechanics, so adding a mandatory dash to everything would just be obnoxious. Though I suppose the fact the whole 'timing' situation just wouldn't work in the context of FFXIV and it overshadowed the whole dash thing. FYI, all the cartridge attacks (except Double Down) have a 'timed' input, 'Continuation'. That is the closest you will get to a 'timed' input.
