I think masters needs more slots per region, regions now are so competitive, and 3 doesnt feel like alot considering ascension over time has added a fair few teams to every region, and that the general quality of teams is increasing (imo)
For example;
In APAC, teams like T1, BOOM, DRX, GenG, RRQ, Nongshim, Talon (and maybe PRX) are all capable of making it and I wouldnt be TOO SHOCKED that they did
In EMEA, I would say Fnatic, Heretics, Vit, Liquid and Maybe FUT/KC are all good enough to compete at least somewhat for the weaker of them
In Americas, KRU, 100 Thieves, SEN, G2, C9, and MIBR are all playing really well and have a REALLY solid chance at doing something or other
In CN you ofc have EDG, but right now certain teams like Xi Lai, BLG, Trace, and TEC are all quite close, Wolves been decent, DRG and FPX not awful (though the region definitely lacks in some ideas, and is heavily aim focused atm)
Idk, I think more slots is a positive in many ways, I also think Champs should inevitavbly gain more too to make it more of a big event.
