Hi, first time poster here,
Switched to playing Boomkin midway through ToT, and always played/spec'd the standard way as this and ej's forums advised.
Played with the crit build at start of SoO clearing upto Garrosh with it, and although never ranked was close a few times, probably might of ranked if I didn't like DoC so much, but anyways I was messing about on the dummies with my dps and decided out of boredom to try a mastery build, gemmed all yellow sockets 320 mastery and all red Int/Mastery and reforged all crit to Mastery where I could this left me at the 10,289 haste cap, 42% mastery and still with 9k crit.
Tried the dummies again and single target dps was roughly the same if not a little better, so I tried both flex wings and was surprised how high my burst was, my overall dps and also how decent the dps was on trash dotting everything up.
I compared my dps to my previous flex run the day before (when I was crit build and had exactly the same gear) and on every fight it was significantly higher especially on multi add fights like Protectors/Galakras (Protectors I was 25k higher then the previous run) and even single target fights I was 5-10k higher.
Am I being stupid? should I revert back to crit, is anyone else playing with a mastery build?
