If they buff war they HAVE to buff the other tanks which is I believe there will absolutely be no potency buffs for any of the tanks the entire expansion. Reason being as soon as war gets buffed players will complain and SE will be in a arms race to buff and balence all the tanks. Right now no one is.complaining about tank DPS and all the tanks are viable DPS wise so like they said in the live letter and by most of the player community tanks for dps aint being touched. Personally I would be surprised if they do any damage increase to any tank until 6.0 and it's not needed it just isn't WAR just need quality of life changes like overpower not costing beast gauge( makes no sense) other then that it's a good job with great potential as the expansion goes on and stats increase
