Don't feel like WAR is really much different than before in comparison. As the game developed through the 1.xx phase... Warrior was typically the SR AoE tank where PLD was typically the single target tank.
Nothing has changed, and the only reason PLDs currently SR faster than WAR is due to Sac pulls. Something SE clearly wants to nerf...
