My issue mostly boiled down to the fact that whilst my shaman, in our heroic run, was doing roughly 28k on Brackenspore with hugely inflated rejuv mushrooms (I'd pull our heroic logs but the ones we have from this week have been done privately it seems); my monk, which was at the time 5 ilvls beneath, did 33.5k on mythic, which is arguably quite low for the class potential, and whilst with abused mechanics on my shaman, and better gear and much more optimized play, I had no chance at even scraping it.
At least I get to play my shaman on Tectus though I guess, here's hoping there's a little more tweaking between now and blackrock at the least
