You're clarification did not help any. I think most people understood your position the first time, but like me found it ridiculous. Is your ideal group just 8 Blasters? Many of us, myself included, find Blasters boring AF to play. Self centered all out dps is not everyone's cup of tea, nor is it the ONLY way to play this game.
I think you should actually play a Dom or Controller at end game before you try to speak on their role in groups. So far all you've done is explain that you do not understand what these AT bring to the table.
