Skill used, cooldown activated, but effects not received.

Used Hallowed Ground, saw the animation, got the effect on my status bar, had the cooldown taken, but still took damage for another half-second, and thus died because it was used in an emergency situation (which is kind of how Hallowed Ground and Benediction are supposed to be used: reactions to things going wrong) and mob animations apparently have priority over skills. This happens regardless of area. Binding Coil of Bahamut Turn 2, Turn 4, Turn 5, Amdapor Keep, Wanderer's Palace, Behemoth/Odin FATEs; I've had it happen at least once (and usually more than once) in my time playing XIV in all of these areas.

I know I'm not the only person this is happening too, and I realize that this issue is largely latency based, but the way these skills (in particular Hallowed Ground and Benediction) work needs to be tweaked so that latency doesn't have as large an effect.

This was never an issue in FFXI; when a Paladin in XI popped Invincible it took effect immediately and there was never a talk of people getting popped for additional damage at the beginning of its use. Why can't XIV be the same?
