EA having a toggle protection is why I picked it over ninjutsu, yeah. I don't like forgetting that one.
Right now I'm leaning toward /EA as the secondary and either katana or staff as the primary. I heard that staff is subpar on a scrapper - is that true or is it not enough to worry about? Also, with a def-focused secondary set, is it worth getting the def-focused attacks (Guarded Spin for staff or Divine Avalanche for katana) or is it just irrelevant? I guess for Guarded Spin you'd want it for the AoE if nothing else.
Edit: Specifically I heard it was much better for Stalkers, so if that's the case I might make this char Katana/EN and save Staff for one of them.
