High five. Someone who doesn't have tracing paper thin skin. Bet you don't mind 1-50 too!
The rage is amazing. One time we matched against this one guy three separate times and he was trash talking from the start. We had two pretty terrible team mates, but managed to carry them and beat him in a close match. The whole game he was raging at us through proximity chat. In the post game lobby we couldn't help ourselves and just laughed at him, which made matters worse (for him). In subsequent games we kept beating him, the messages were amazing. I wish I could have recorded them :/
I like 1-50, definitely. Although I think Bungie's idea with Arena could have been great, stopping all the second accounts and boosters. If either your arena rank showed up in all playlists next to your name with the percentage in it like this:
OR more playlists had arena ranks and were more visible.
Sadly, what we got was an almost non existant ranking system that no one cared about.
