my worries about the new bruiser keystone coming out

so it's been revealed in the precision tree, and the description says you need to be in combat for 4 seconds to proc it. that's already a problem as it is since most of the time i can't tell a bruiser apart from an assassin without cc being involved because of how squishy people build them, but when it does proc it gives a certain amount of ad, and turns a certain % of damage you do as true damage. that's nice, and all but seeing as how people are complaining they aren't doing much damage to tanks as bruisers. that means you will do true damage to them, but it will be low as well, and can get even lower since the true damage they take is affected by the damage you dealt to them in the first place
