monk is a tank in the party finder. i don't know if monks will do the highest dps mr stark.
a guildy (tank) complained that monks basically always mash taunt in their 123,123,123ing, so they snatch agro all the time. that's the comment i have from higher level folks about them. they mash taunt.
I don't know if they are meant to be actual tanks, or if they're just a bit of jack of all trades. I kind of want to play at some point to test, but i don't know that i want to spend enough time to get to high level to test if they're meant to tank.
