Whenever someone says Marksman Hunter, Ret Pala, Frost DK, Fury Warrior are the top DPS in charts, its said for end game content.
on i200 level items, MM hunters are not on top charts, as they start to build up in proper terms after i226 when the physical damage overcomes the spell damage. Till then its a pain and stress, because whatever you do in your right rotation, glyphs or cds .... you wont be hitting on that par like others do or a surv hunter does .... and movement or mana drains will hurt your dps more
