Halo 5 Banning me

So I was playing Halo 5 and one of my friends got on. He invited me to play Halo 5 when I was in a match, so I was thinking quitting one game won’t hurt. So when I quit that match I was banned for 8 hours. It was the only match I quit for that day. Do you think they should fix this and have you banned for 1 hour if you quit 5 matches? or should they leave it like this?

You have 15 quits in the last week, I think it is working correctly.

Please use the ban thread pinned at the top of the forums for any ban queries, thanks
