Probably the worst MMR system for a donation server

Here to start a voting process for a MMR system that is connected to your gearscore (GS), or some other design for it that will stop full BIS chars showing up at anywhere between 0-2200. It is a system that in its current form is unfair and unenjoyable to any newcomer (new wow player or new to server), and it creates imbalances as to be unable to gear up, especially when combined with the most horrendous elitism i ever met on a wow server, as most players have some overinflated narcissistic image of themselves (everyone is 3k+ XP but most of them can't even pass 1800).
Have you donated for an item that is normally requiring 1950? (Helm), or 2000?(shoulders) or 2200?(T2 weapon), then you should never be facing people lower than that (narrow margin is fine, ~200+/-).
I have nothing against donations, as some ppl have busy lives and no time to farm honor and grind ratings and AP, and i do not consider them a Pay 2 Win system, EXCEPT in its current form, where people with 0 skill, backpedalling around, but with smourne and full wf gear just bladestorm and relent players just die left and right.
On the other hand, most old players who are in BIS gear and/or have good knowledge of the game prefer to play the i-don't-know-how-boring-that-can-be same old 50 ppl multi-classing at the top, and just telling people who are learning the game or new classes/comps to just "delete the game", "go die" or just throwing trash talk at whoever is not in the same league as them, rather than bringing anything constructive to the game and this server, community wise (SoloQ), and bluntly refusing to help anyone gear up or skill up.
And since we're on the MMR topic, i know other servers implemented MMR to BGS, as to create a more balanced and enjoyable full pvp experience across the game, perhaps it's time warmane brings that on as well instead of this terrible mercenary mode.
I think changes that will allow more new players to come to your server and enjoy PvP will bring more donations than some 3v3 competition where you spend 5000 $ on old farts who are grinding the game since 2009.

Thanks!

EDIT: For god's sake do something about stimulating 3v3, such as increased arena point/rating gains or whatever the community feels like would be rewarding to move away from this boring trash 2s
