I remember trying to solo a nightfall in year one, Archon Priest with solar and void burn (this was before I had any elemental primaries or ghorn) and I had gotten the Archon down to maybe to 5% health, and I got 1 shotted by a Servitor I had forgotten to clean up. This after wiping about 6 times. I got so mad I threw my controller into my dresser and broke the -blam!-er in half, it's the only time I ever raged that hard in a game. And 50 dollars later I learned my lesson, to just calm down and keep my saline levels to at most 7999. TL:DR Op is correct, raging is just going to ruin your game.
