The general idea is that you pull in grit, establish enough of an aggro lead, then drop it when safe to do so, and push more dps

it only works if you're in a group of people that know what they're doing tho, eg healers knowing when dmg is coming and mitigating, you using your cds appropriately, dps using aggro reducing abilities when they should, etc. And you rarely/never get that in df

other times you might need to use grit as an extra cd, or if you're close to losing aggro. drop grit obv if there is a tankswap and you become the ot
