It's time for another episode of "I don't know what the fudge I'm doing!"

So much to my misfortune, most of my SSR are defender. My question at this point (my best element is water if that matters, you guys helped me decide that earlier) should I skill up SR water weapons with assault since the only other option is defender? I mean, I have the bow from Tiamat, but I barely started during that even so it's not even broken once.
