Hate Gain has a hard-cap at 100% which is effectively double what you would do at 0%. Anything above that doesn't help. As a side note, Hate Gain also has a hard-cap at -50% (half what you would do at 0%) for those DPS toons who want to avoid getting hit.
really? but i think - 150% (because mine toon has minus 148%). but nevertheless this doesn't mean that mobs pretend not to see him
Fighters have an ability called subtle strikes which takes their hate to -150%. It's to drop aggro on stuff, later raids have tank swaps, etc.
it's just a tool that fighters get to help from taking agro on the named or in helping to swap agro with another tank.
