I'm really, really concerned about this. I love PvP, but only if it's playable.
I'm HOPING that the video was 'slow' to show off abilities for people who are new to pvp... but the part of me that already knows about the delay issues is forced to speculate about what would happen with players in PvP.
I'm really concerned about the natural delay of this game. If you try to use an instant ability with a close range, it will be nearly impossible to land on a constantly moving mob. (I first discovered this while trying to use Fluid Aura on a kited mob as a healer.) In other MMOs, melee players jump around casters and other melee in order to make it more difficult for the other player to get a spell/ability off. If that is done in FFXIV PvP (and I'm assuming it will), it will be very difficult for a player to score a hit if another player is dancing around him/her. Players with long cast-times will not be able to play well at all.
