I have absolutely no problem with you running shroud the way you want to run it. I run fast shrouds too, i think 15 minutes normal is my lowest. But I like teamwork, and I like running it under level, in hard or elite with pugs. Bad habits are bad habits, and running overgeared can teach bad habits. That is what is happening. And when I lead a raid and say no wail, it means no wail. You can always start your own lfm and complete faster than me. Have fun.
This is why I always told my guildies that nearfing the blades was a bad idea. Not a fan of autocomplete on all runs.
