Tank stance on syncing down

[Shurrikhan]

The reason is very simple: the game makes sure to remove all buffs related to skills and abilities to ensure that nothing of too high level stays.
And the game also doesn't seem to be willing to parse through all of them to see which ones are on level and which one aren't.
Since tank stance is lvl1 however, they could frankly exclude it from the whole process...

Or even purge and then just auto-apply it...
