I'm a kin fanatic, and I've never tried arsenal yet, but I'm thinking of pairing both together to see how that goes. Kin is probably not an ideal secondary to most, especially from the comments I've seen on other forums, but who cares, what's there not to love about Kin? With stealth built in, I can just run in and fulcrum, heal & end sapp. I've already made a build in mids, it's got perma haste, S/L res capped at 75%, 45% on ranged def, and psionic mastery for Indomitable Will to avoid those annoying mezzes. I'm looking forward to it 🙂
