Someone correct me if I'm wrong, but I believe wars have higher stamina totals. Avoidance should literally almost be a non-issue since they are going to be using the same gear. However I did read (no link sorry) that with the new shield block and with the talent critical block, wars are showing to mitigate more damage overall.
Wars are still absolute beasts for single target threat. I don't believe this has changed, and palis got hit with some recent nerfs that seems to have affected their dps and tps.
If anyone has anything more in detail pls share. I have no real hard numbers to back myself up here.
