Hello,
I'm new to this forum and I need help to the following questions, hope this is ok

1)With the new patch can we raid with BM spec? i.e. do we put out enough dps
2) Does MM spec put out the best DPS?
3) Is mastery worth reforging for?
4) Is haste worth reforging for?

Thanks for the help, I was ...
