It was either nerf PLDs down to WAR levels or buff WAR to PLD levels. They chose to buff.
This brings WAR base TP consumption more in-line with PLD. How is more wiggle room with TP 'pointless'. This allows you to more freely Over Power during fights with less reliance on Flash, maybe even trade Flash in for something else now.
Same reasoning as above.
This is very much needed and in no way makes WAR 'OP'. We currently have no significant pro-active defensive abilities when compared to PLD.
This is just to make it a more attractive choice when cross classing it. More frequent use during trash pulls.
The change to IB still promotes intelligent management of Wrath stacks even more so than it did before. Spending/building Wrath will be much more meaningful now. Having the healing bonus attached to stacking Wrath was contradicting. With the healing bonus now attached to Defiance our tanking stance is now more equal to a PLD's Shield Oath in terms of healing efficiency.
A free of cost AoE snap threat move that looks great, it was next to useless before hand. Over Power is a frontal cone, Steel Cyclone hits everything around you, it's a quality of life change as well.
You may be sitting pretty now that you're wearing a majority of level 90 pieces but PLDs were doing what you're doing now in full Darklight with far less effort and stress on the group.
