I'm kind of impressed by this, though you're not alone. There's a huge mentality that is uniquely prevalent in this game, where tanks get themselves to the point where they can survive the tankbusters (even if only barely) and then throw everything they have into offense. Don't get me wrong; there's certainly nothing wrong with it, it just doesn't make any sense to me. In every other game I've played, tanking has been focused the other way. You do just enough damage to where you can hold hate, and then do everything in your power to mitigate as much damage as possible, even if that means doing less damage than you otherwise could have. It's why my main ideas for improving parry focus on making it a better defensive stat, instead of scrapping it for offense.
