The new system is very simple, elegant and VERY effective. Too many people are making it overly complex. Here is the break down:
Seals:
A buff that is placed on your character that lasts 30 seconds.
It only goes away when it times out or is removed by some other ability from a mob/pvp player.
If you have the Ret. Talent: Sanctified Seals (3 points) your seals cannot be dispelled/removed.
Judgements:
Three different spells that can only be used when ANY seal is active.
All three spells share the same cool down.
The JUDGEMENT spell, not the active SEAL, determines what new debuff goes on the mob when judged.
All JUDGEMENTS do base holy damage regardless of what seal is active.
Example A)
Paladin runs up to mob and starts attacking with weapon.
All 3 Judgement spells are greyed-out and unable to be cast.
Paladin cast Seal of Light.
Seal of light buff is now active on the Paladin & ALL THREE JUDGEMENTS (Light / Wisdom / Justice) are now available to be cast.
Paladin chooses to cast Judgement of WISDOM - three things happen:
1) Seal of LIGHT stays active on the Paladin
2) Judgement of WISDOM DEBUFF is put on the mob
3) Mob takes base Holy damage from Judgement spell.
End result: Paladin has seal health regen buff on attack swings, and mob has wisdom regen debuff on attack swings.
Example B)
Paladin runs up to mob and starts attacking with weapon.
All 3 Judgement spells are greyed-out and unable to be cast.
Paladin cast Seal of Vengeance / Corruption (same spell, different faction names).
Seal buff is now active on the Paladin & ALL THREE JUDGEMENTS (Light / Wisdom / Justice) are now available to be cast.
SEAL DEBUFF is placed on the mob next swing doing holy damage over time.
Paladin chooses to cast Judgement of WISDOM - three things happen:
1) Seal of Vengeance / Corruption stays active on the Paladin
2) Judgement of WISDOM DEBUFF is put on the mob IN ADDITION TO THE SEAL DEBUFF.
3) Mob takes Holy damage from Judgement spell, which is INCREASED by the seal having an "on judgement" damage modifier.
End result: Paladin has cause holy dot on attack swings, mob has holy dot debuff (from the seal) AND regen mana debuff (from the judgement).
Side note: Seal of Vengeance / Corruption are now 100% proc on swing, not "chance on swing".
