Tank Stance

[Asiragan]

Diversion is a 90% reduction on your personal enmity for 30 seconds every 120 seconds; it’s ridiculously good. Using it on cooldown does wonders for both yourself and your tank. Refusal to use it because it’s “not my job to management aggro” is just refusal to be a team player.

Not only that, but it's also part of the DPS job to manage their aggro. Usually, the good tanks like to switch stance to dps some more. But if you don't manage your aggro, the tank can't switch resulting in a dps loss for the party. Plus, it probably won't be fun for the tank that will try to keep the aggro when the DPS are using their opener.

I guess those who don't are people who "play dps because they don't want responsabilities".
That's hard to hear that everyone is responsible for a lot of thing in a party.
