I utterly disagree that CL is horrible. For boss fights, maybe, but on trash if I don't use CL my recount DPS drops ~500.

I'd also like to keep this MOSTLY on topic for multiboxing. Timers, perfect rotations, etc, are all moot points for 5 boxing IMO - no one is going to get the exact optimal rotation with 4 shamans and a tank unless they're using cast sequences which have their own major latency delay. I think most people here (when 5 boxing) use castrandom or castsequences so talking about needing X haste to make this exact rotation work under 100ms latency is kind of silly. It might be helpful when solo boxing but not 5 boxing.
