Ranking System Is BS 343

Ok, Why can’t we have the old ranking system? good old 1-50…Whats wrong with that? This new ranking system for Halo 5 Guardians is god awful. Im " Semi Pro" close to being “Pro” which is close to being a 50. Which I was pretty fine with it until I started to learn how it worked. So to keep your “pro” basically your 50 which you earned and should be able to keep and play on anytime against other " Pro’s ". I have to keep playing that ranked playlist over and over and if I have something happen where I have to stop playing for a couple of days. Saying I get deployed or have a family emergency where I need to leave and go back home for couple of weeks . Or something crazy happens/anything it’s life. We can and will lose our " Pro " Skill rating cause we weren’t able to play so we’re gonna get penalized.I rather have True Skill Ranking system back then Leader Board style ranking system. This isn’t HaloTracker. So basically if you don’t keep playing your gonna lose your Skill Rating as rather then keeping it. I have a 50 in every playlist in H3 maybe for the exception of few. I’m sorry, Im a U.S Service member. I have to leave and be gone for months at a time I would like to keep where I left off or when I get to where I’m going I dont have to worry from going to Pro to Semi Pro back to Onyx 1 working my -Yoink- off back to Pro. You basically have to no life one ranked playlist to keep your rank. How is this fair?
