You're not doing anyone favors by solo playing bosses. You are in fact wasting everyone's time. Players who fail mechanics don't deserve to lie on the floor and not get a chance to learn the fight. They don't learn their own job by watching you finish the fight either. Moreover killing a boss "near death" is not special. I can do that on a BLM, and I have. Most jobs can under certain conditions or very low time limits. The problem with WAR is it is designed to solo down group content far beyond "near death". If anything I hope you get reported next time you do this (if you're doing it anywhere beyond a few % hp).
Yoshi P really needs to get this tank messiah complex under control. You said, and I quote "I had to solo the boss". You actually don't. You didn't have to do anything.
