Not like I want to use Monomyth for WW PvP, but I wanted to test it at least, but...
When you enter WW form from the frontbar, Monomyth is in backbar mode.
When you enter WW form from the backbar, Monomyth is in backbar mode.
Maybe devs didn't think about Monomyth + WW combination?
Maybe intended?
What do you think?
In my opinion, Monomyth in WW form should be in the respective mode from which bar you entered the WW form.
So you should be able to choose which side of Monomyth you play.
Because WW is kind of sub-bar/ultimate-ability, it's not really a 3rd-bar/backbar.
