Team Build: 7 Hero General

So, I've been meddling with PvX wiki later, and found a very nice hero team build on Illoyon's Sandbox, and thought to try tuning it a bit.

Can you give me some feedback/suggestions about this work?

Shud work, just not very font of SF Ele's but its optional.
Try 3 necs 4 rits or vice versa, Otherwise balance or mesmer stack.

Those are usually garuanteed winners.
