Requires 1 point in Crusader Strike
Requires 45 points in Retribution talents
Gives the Paladin's Crusader Strikes a 50/100% chance to increase the target's Global Cooldown by an additional 100% for the next 30 seconds. Stacks up to 5 times.
Effectively, hit the target once with CS, and her GCD becomes 3s (2s for Rogue/Cat), 2 hits for 4.5s, etc., all the way up to 5 hits for 9s. (Assuming zero Haste, of course)
It's something that no other class can do. It messes with tempo, slows the fight down, and is anti-burst. It hurts instants more than spells with cast times. Yet at the same time, it doesn't affect a specific individual spell, only how often you can cast spells. It sort of becomes a counter to the Haste stat.
I have no idea how this would work with mobs. It's probably a PvP-only thing.
Thoughts? Would this actually be worthwhile in PvP, or should I get more sleep?
