Seal of Corruption changed:
Quote
Seal of Corruption
14% of base mana
Instant cast
Fills the Paladin with holy power, causing attacks to apply Blood Corruption, which deals [(0.013 * SPH + 0.025 * AP) * 6] additional Holy damage over 15 sec. Once stacked to 5 times, each of the Paladins attacks also deals 33% weapon damage as additional Holy damage. Blood Corruption can stack up to 5 times. Only one Seal can be active on the Paladin at any one time. Lasts 30 min.
Unleashing this Seal's energy will deal [1 + 0.22 * SPH + 0.14 * AP] Holy damage to an enemy, increased by 10% for each application of Blood Corruption on the target.
Exorcism changed to a 1.5s cast. Time to wait for Art of War to proc - which does send up an SCT alert.
Crusader Strike costs less mana, has a faster cooldown, and does less damage:
QuoteCrusader Strike
5% of base mana Melee Range
Instant cast 4 sec cooldown
Requires Melee Weapon
An instant strike that causes 75% weapon damage.
TL;DR:
Use Seal of Command where you need to have explosive damage.
Use Seal of Corruption when you have the time to build up to 5 stacks.
Oh, and Vindication is no longer as cool as it was. I really loved that spell in PVP.
I see that the Seal of Command glyph gives mana back like the old Seal of Blood glyph did. I'll have to pickup a different glyph now since I don't really need less of a cooldown on my holy wrath.
There was talk of people twisting seals to try and pimp out that extra dps - Not sure how that ever worked out, or if it's feasible at all.
