I know there was a post about how abilities and x factors are overpowered and i tend to agree with that but i have to say 0 ap momentum shift is really dumb - the AKA version 6 AP is pretty bad too
the whole point of the combine promo and AKA cards (with basically everyone being 99 speed with crystals) is that they got starts on or unstoppable x factors - having literally 1 free x factor that completely counters that is really dumb
it also incentivizes really dumb stuff like starting the first play of the game with your backups all in - i think it should have some sort of activation requirement like a sack or a pick
EA is obviously not going to do anything about it, so I would recommend everyone run it - its 0 ap and you have to sub the 96 Cushing in for the first play (not kickoff)
