PLDs might barely be able to hold all those enemies, but we have always known that it was much more of a single target tank. Flash is meant to be a helper for establishing initial threat, not a solution to AOE tanking.

I think what a lot of people are forgetting is how stats work. With a WAR, every single attack you have is classified as a melee attack. Melee means it benefits from your strength. More damage = more threat. But for a Paladin, Flash isn't a melee attack, it's an offensive spell. That means it uses your Intelligence, not STR. That's why we all see such a huge difference between the threat we get off of Overpower compared to Flash. Shield Oath gives a huge improvement to flash when you get to 40, but the more you gear up at 50, the gap between overpower and flash just grows larger and larger. It's a bit of a design flaw that will become more and more apparent the further we progress.
