Channeling & Communing Ritualists

Here's the plan:
1st Ritualist with:
12+ Communing
12+ Spawning Power
2nd Ritualist/Mesmer or Ritualist/Elementalist with:
12+Channeling
whatever else you'd like to fit in

1st ritualist uses spirits like: Pain, Disenchant, Bloodsong, Shadowsong, Wanderlust, ect.
2nd Ritualist uses the hex "painful bond" and one of the echo skills or glyph of renewal with spike skills in the mix.

Any ideas on PvP or PvE applicabilities? Suggestions? Comments? Feed-back is appreciated.
