Well formatted mastery points - quick QoL improvement

Hi,

I believe the mastery points in the loading screen should have better formatting.

Often it's hard to quickly judge whether the person has 1222222 or 122222.

What I suggest is to have a separator in those numbers, e.g. 1,222,222 (or 1 222 222).

This is quick a fix from game dev's point of view, and it helps the players to quickly judge the opponent's experience.

Do you find the mastery points hard to read as well?
