Well seeing solo players doing things like
50% haste
50% Twilight Dev tanks with 1million+ health
Versatility stacking
and such, things are getting ridiculous.

I want to try and stack 50%+ Leech on my DH's, and maybe full Infinite Stars on my druids. Still wondering what would be good on the hunters. Is there a cap on range with Marksman hunters mastery? How funny would +50% mastery to all source be on MM.
