1)I have used wowreforge.com with the values; Crit:2.0, Mastery:1.9, Haste:1.4. Always gets me to hit/exp caps.
2)
Code:
#showtooltip Misdirection
/cast [@focus, exists, group] Misdirection; [@pet] Misdirection
Is the macro I use, MD to pet when no focus and MD to Focus(Tank who pulls) if exists.
3)There is no DPS difference between Iron Hawk and Normal hawk. You just get 15% damage reduction. For Soloing/BGs/Dungs, I'd take Spirit Bond, for Arena/Raids you want Iron Hawk, do not underestimate the passive damage reduction.
4)I usually do 1 Multi-Shot, then Explo trap as BM, however the rare case of me being BM for AoE fights is pretty miniscule.
5)Don't bind Rabid to BW, you lose uptime on Rabid.
6)Get very good practice for the starting rotation, you have to nail it to get a good start and increase your DPS overall for the encounter.
