and im going to post up a build i made in a little while
WP/Stone seens like a reasonable combo. Fault lets you shut down a spawn while keeping it nearby, which gives RTTC a chance to get you back up to full. The stuns and KD in the other attacks should help with that too. And QR should let you cope with the somewhat high endurance costs of /Stone.
Only downside is that Stone Melee doesn't really shore up WP's problems with holding aggro. Tremor's terribly slow to animate, and the whole set is slow-recharging. Add that WP doesn't really benefit from +recharge, so building for a lot of it is a bit wasted, and you might find it a little hard to stay the center of attention.
Looking for some help with a wp/stone i have at 50.. not sure if /stone is anygood.
