Sparring Seasonal League

So. I already know that there's daily weekly and monthly spar scores but how about we start leagues?
Such as Silver 1 - Silver 5 then Gold 1 - 5 then Platinum or whatever etc.

Players will be required to win atleast 100 spar wins in a week to participate.

POINTS SYSTEM
-----------------------

Once they're put in a league, the way to rank up a tier isn't by spar wins but by earning points by overall progess
Of course it will be hard gaining these points as you won't receive one over a single spar but you'll receive a point based on your performance over 10 wins or maybe performance over weekly amount of matches won
And from that it will give you points from it. Also, if a player is suspected for boosting and evidence which is beyond reasonable doubt then points which they've gained from boosting will be deducted. However they will still be able to compete with other people in their skill tiers. Since for example if they were in Gold 1 and boosted to Gold 2 then the points they gained would deduct and put them back to Gold 1 as instead of just removing them from the leagues would be unfair as they may have gained their wins legitimately first.
If caught boosting again or strange anomalies are found in their records and investigated to be illegitimate then they will be banned from the current season.

Match Ups
-------------
Players will be gain more from a league that's higher than theirs and gain less from a league lower.

Players will only play against people that are their tier, 1 tier below them or 1 above them.

Maintaining Tiers
--------------------
Ranks will last for possibly 2 weeks and you must spar achieve 100 spar wins atleast in a week to renew your rank. However, the majority of readers would most likely say "Oh but you can just gain 100 wins then you won't need to spar for a week to keep it" Wrong. You will be deranked if you don't gain any wins/points frequently. This league isn't meant for lazy people, if you want that rank you have to earn and maintain it. However you will be allowed to not spar for one week if you choose to since players may have certain problems which will hinder them in this. So you can call it a "Golden week". You may only have 1 per season though.

Seasons
--------------
Not sure yet but instead of monthly, these leagues should be seasonal. Which will also mean that rewards will be bigger for maintaining higher ranks.

Rewards
-------------
Silver tiers - Gralats, 1k-3k
Gold tiers - Gramats 4k-5k
Platinum - Gralats 6k-10k
Masters - Gralats aswell? Or possibly 5-10ec? TBD
Top 3 - A trophy/Gralats/EC TBD

The rewards are fairly high since your maintaining these high ranks for a season. Not a month.

Postscript
--------------

This is only an idea, however I would prefer if you commented something constructive rather than saying "Unneeded in era" or "Who cares about this" -cough- xStarx -cough-

And yes I know, we already have Spar rewards so it might deter players from this idea.

Also the points system may already be too hard to actually program since you have to create an individual tracker for every participater probablg
