The 12 second DOT, ability to tag multiple players, being able to tag/shoot/move on with your gameplay whilst guaranteeing your kill, and the ability to have one of these every 30 seconds is what makes it over powered (However, it is necessary for the class to have. Take that away and they're nothing). Don't ever compare firebolts to a wombo combo. They are nothing alike and if you have trouble escaping one, then he got you good or you were not playing correctly.
