This is a huge blow, that passive pretty much make the entire spec and to not get it til very late is insane

Arsenal still feels like it self. The way you have designed the trees with first a main ability and a mod for it is a nice way to customize things a bit i feel, and i am ok with having to make some of the higher lvl choices. However i do feel that every class should have certain abilitys and one of them is a hard stun, this should not have to be a choice. I have also seen some classes have their big raid utility as a option in the trees which i feel is very odd
