What exactly are you getting at and why is that interesting? Lots of people solo crota legit, lots of people do it with a friend as a 2 man team legit. Lots of people do it as a 3 man team legit. Whats your point? I'm thinking you feel that means he has cheesed the Crota fight himself, it doesn't even remotely let you infer that.
He is making assumptions of people who cheese crota. Go look at the recent raids on his two highest level toons.
Neither one has raided in the last 2 weeks with more then 2 other people.
SO, thinking caps on!, hes cheesing and then trolling everyone else.
If you are going to tell me that he can 3 man it with a 29 a 30 and one level 32 in the group, im going to say your the biggest bag of hot air on the forums.
