Wrath of the Arbiter
Your Holy Wrath spell will now change properties based on what seal is currently active.
Truth - Single target strike that deals X% of weapon damage (physical) plus X% per stack of censure. (holy)
Righteousness - Sword crashes down dealing x% holy damage to all enemies in front of the paladin (frontal cone, similar to cone of cold). Maybe toss in the demon/undead stun in here. This is our AOE seal anyway so we'd be wanting something to this effect, it would also make us more mindful of positioning when we use it.
Insight - Single target strike that deals X% of weapon damage and heals the paladin for x% of total health (a sorta death strike Esq move). Rets need another way to heal themselves and a 15 sec cd pseudo death strike wouldn't be too shabby.
Justice - Something PvP related. Like a 10-15 yard weak distance strike that dazes the target for a few seconds. Paladin's have a hard time in the 10-15 yard range in pvp. LaotL only reaches for 15-30 yards, and it's relatively easy to kite from that distance. Some relatively weak semi-ranged ability would do wonders. It would not only cement this as a solid pvp seal, it'd synergize well with LaotL and the relatively weak running debuff the seal offers.
Doubt it would happen, and if it did it would have to be heavily tweeked or overhauled to not be too over powered for both PvE and PvP. But to be honest I don't really know anyone who likes the new Holy Wrath, and something like this could fix some of the issues ret's still dealing with.
