Idea for fixing Rank system and de-pipers

This is a suggestion not sure, was thinking to make a yt video of this might want the community suggestion first:
this is ALL self opinon

What if:

• Hitting Rank 1 gives you like a cosmetic just 1/3 parts end of the month, doesn't have to be a good cosmetic, just a symbol of Rank 1 of that month.
• When you are in rank 1, you CANNOT de-rank out of it. Which people that has a decision of either getting the cosmetic that you can never get again or de-ranking on purpose.

What problems would this occur?

• people can de-rank than push rank the last minute.
• people may or may not want the cosmetic but using as an idea that you can ONLY get this cosmetic on that month of a life time, it is a mark of rank 1 of that month.

Solution to the problems:

• If there is something above rank 1 or make point system more strick
• if you hit a certain thresh of ranking you can't go back down. Example such as hearthstone: once you past a certain rank you won't go back except by rank reset.

Main issue with people rank the last minute after trolling lower ranks is: people at that rank will be more sweater that usual. The competition will be harder, i believe the point system we have now is pretty legit.

The concept of this ranking is literally a hearthstone idea, it won't be a copy due to the fact there is SOOOO many rank system, and DBD fits in the HS ranking system. Unless DBD has a rank + ban system or with Casual match off course another rank system can be occur.

This is an opinion, I know this is alot like HS, but after watching the pod cast of king, Jen etc etc. This will save lobby times for everyone, which i believe.
