I know i am not the guy this is directed at but i am currently pushing 2k rating (2.1k mmr) and i only gave it a real try in 3s yesterday. (team 1900 atm and 2s with some crap mage is also 1900). Routine seems pretty solid (i went with donation version) could do with a few tweaks which il message Richie about later after we hopefully hit 2k.
One thing that hasn't work at all for me is the swd sheep but i am not to bothered about that as i use a /stopcast cast swd macro which is great if u end up fake casting penance tho obviously i try to bate a interrupt on flash heal

. Main thing with any healer is your positioning imo and when to trinket. Also i do life swap me self its to big a cd to have automated imo and i think il be heading that way to with pain sup. But overall i highly rate this routine IMO its the best healing routine for priests currently and best i have ever tried.
*****ing job richie thank you and il message you later with any tweaks you may wont to consider either way its still 2k viable imo (tho i am running a spell cleave and i have played priests at 2k rating of and on since wotlk ie when i haven't quit the game lol)
