Lagged out of one game, lost two whole ranks

why am I being punished so harshly for lagging out of just one game, I have quit about 3 games ever in halo 5, lagged out a hand full of times (January was worst) but recently I hadn’t been kicked or banned (that I can recall, think I got a couple of seconds ban last month for a lagg out), why should I loose two whole rank levels just for one lagg out. I’d understand and support this if It had happened a few times. Realy disjointed as the grind was long. Real sour with 343 right now. I am not a quitter and shouldn’t be punished to this degree!

Sorry, obviously frustraiting and delirious from lack of sleep, I read my game rank wrong haha, I only lost half a rank. Never mind. Sorry for the rant.
Admin team you can delete this if u like I just don’t know how.
