I am playing a WB right now and considered Fireclaw, but it needs (has) loads of synergies, so if you also plan to put points in Lycant, Oak and maybe a decent Grizzly...you have spend already easily 40 points. Shockwave is not too bad, 5 points there maybe.
This leaves you with about 40 points in Fire tree, the claws itself and a synergy. Apparently a 6 Shael (or 4 Shaels, 2 15 IAS + ED jewels) Phase Blade let you swing at 4 frames - outshining Zealots (or so the Druid Forum claims).
At the start, Sigons gloves and, say, Shield are a must. LL and 30 IAS. My build can take it easy, as I have the backup of a caster Party..so I mainly stun and have the Grizzly attack and the raven poop on monsters :lol:
HF merc to go with this build, maybe...? If you are slow, monsters better be as well. (or A3 ice merc for solid ice chunks?)
