The Reach campaign is awesome, the multiplayer is meh.
I find your muting reason an irrelevant reason to why the MP sucks
You only get banned if you get booted a lot, or quit alot, which means you're either a jackass or rage quiter if you are getting banned a lot.
Same with muting, your clan tag reason is irrelevant to why the MP sucks.
