The vengeful healer in me admits to playing chicken with health bars when people don't dodge or tanks refuse to use cool downs. You can't heal stupid but you sure can /not/ heal it. I find that works a lot better. I also admit to getting so fed up with people that they mysteriously died and were left dead on the floor of the last boss as a farewell present for standing in every red circle they could find or getting nasty with my tank. Nobody puts my tin can in a corner.
Meanwhile the clumsy part of me totally owns up to getting frisky with the cleric stance button and occasionally causing a near death, casting benediction on myself by accident, forgetting to lock my bar and removing Cure II /AND/ Medica II mid boss, dropping my mouse mid boss and trying to quickly recover without it only to walk right off the edge of Titan hard as well as numerous other offenses that no one probably noticed but that left me doing that cat thing where you try to walk it off with dignity. Yep. Totally on purpose folks.
