SamSpayed:only those who stream, should get to go to the Live Series finale each month.
I could be wrong, and I understand your point... but from watching the first live series that was invite only... the players were playing from their homes and were required to connect on a stream so the match could be shown live. No one went to a single site like vegas to play.
So anyone participating needs to be able to have a setup or computer that can stream even if they dont do so regularly.
Now your other point regarding tiers has more value... WGT appears to have imposed some serious increases in the ranked round requirement to be eligible for promotion. I have read TL is now 750 RR, when it was more like 200 before... that is an awful huge jump ... and it will seriously slow down promotions.
