[Hunter PvE] DETAILED MM hunter Raid Guide

[Samsom]

Is gemming into ap very bad (40ap)? i've always gemmed that way because mm got 110% attack power (trueshot aura) so it would buff my gems the most, and agi for survival because surv buffs agi the most (expose weakness and Lightning reflexes), but to the point i use the same rotation as stated in the guide and i got icc/toc gear got 335 arp without gems and 6.1k ranged ap self buffed with gems, would it boost my dps alot if i gem agi or arp as told in the guide?
wut shall i do =)?

PS; sorry for my bad english :/
