i will ask a stupid question, do the difference of dps is that big? not really... that the whole point. do the dps of the tank change a lot the team survivability i'm not sure, yes the nin transfert of hate help, but the tank dps is far to be the most important (about 1 k less than the lowest dps)
generally outside the sam, the dps is comprise between 3500-3100 in average... what bother people that now a new meta did appear and them favorite is not inclued into it *shrugs*
