So after copying my paladin over to PTR (
Armory Link: WoW Progress reports me as one of the highest geared ret paladin atm) I can honestly say I very much hate these changes atm.
The new Crusade just isn't a single target damage boost anymore, over the alternative of vanilla Avenging Wrath and Divine Purpose. The new Crusade is however a fantastic cleave talent, that can be made into a fantastic AoE talent when also taking Greater Judgment, but it's single target application just pales in comparison to our current iteration of Crusade on live.
I should add, my PTR Crusade tests were done with an 845 Horn of Valor and a 30 second Crusade to sync up to it, thanks to artifact pathing and 1 relic slot. Even with +2825 strength during the whole Crusade window, I was still pulling less single target DPS then I do on live with the same setup.
The Blade of Wrath change is actually a DPS increase as far as my limited testing is showing on the target dummies. However alongside the changes to Crusade somewhat forcing us back into Divine Purpose, this leads to a spec where we are now watching for 3 proc's and failing to press the right button leads to a lot of DPS loss.
Needing to watch for Fires of Justice proc, Blade of Wrath proc and Divine Purpose proc while rewarding when executed properly, feels like ass when you miss a proc or delay a proc when a better proc happens just before you activated another skill. Which when juggling 3 proc's happens quite frequently.
The fact that our 4 set also adds a fourth proc, this spec very well might become a complete RNG lotto that will have zero consistency from boss to boss.
