Has anyone seen or done and math on Haste breakpoints? I was doing some rough math (really rough btw) and I'm coming up with 8.33% (~3541 Haste) as the first breakpoint for a 7th tick of ReM. What's interesting is the effect Haste has on ReM. The closer you get to the 8.33% point, the faster the 6 ticks hit, then once you get to that number, the HoT goes up to give you the 7th. I was seeing sub 17 sec HoT uptime before that breakpoint and 19 sec plus after it. When you check the combat log, it does indeed change from 6 ticks to 7.
Looked all around for some nifty spreadsheet, but have found nothing. Thought I would share my findings.
(If I'm way off, apologies. Again, rough math :P)
