Sounds like a fucking hoot tbh. Going to be extremely difficult to choose which job to main this xpac. I main drk rn but still enjoy War and Pld, however Gun is going to be competing hard for my attention. Good time to be a tank

[Alkar]

If its LB3 is called Lion Heart I may have a new main, everything else is there! Demon Slice is just the icing on top lol.

[Scythiroth]

I guess it could be called that, but it will be a defensive one because tank.

[Alkar]

Eh, I'm fine with that. Tanks seem super fun to play this time, except WAR maybe.
