I have mentioned this in other posts.
I would like to know if Master and lower tiers have this issue. It seems like it is usually TC and C tier that have the most problem with this.
My theory is that there is an algorithm built in to coin rooms that delay higher tier players when there are more high tier players in the room. It seems that this is WGT trying to match higher tier players together when possible.
Then again, what the 😈 do I know.
