Going with a stat priority of crit>mastery>haste you can get 80% eclipses on both sides. My druid has CRAP gear and im topping BG damage charts already:
478 ilvl and im already critting over 100k starsurges.
Yes you give up being able to be a healer every 6 min for 45 secs but you get at least some of that survivability back from 20% to healing touch, and the damage you gain from the 6% passive int on HOTW is far outweighed by 25% to your eclipses.
I armoried all the top balance druids and not a single one of them takes cenarius, its not hard to get off healing touches and the buff lasts 30 secs before you need to get into a new eclipse. I cant imagine the damage i will be doing in full grievous, it will be pretty crazy, i may even try a mastery>crit>haste stat reforge if im getting enough starsurge procs to use properly.
