Statistically, China is the best region so far. And EMEA is the worst region. Rest are Mid. Teams in playoffs:
Americas: 2 out of 4 (50%)
APAC: 2 out of 4 (50%)
EMEA: 2 out of 5 (40%)
China: 2 out of 3 (67%)
yo BLG literally just did better than the pacific LCQ winner Zeta while being in the same group. EDG and BLG surely would've qualified if they were in pacific, and plus China wouldn't be a region so there would be 5 slots for pacific, meaning they definitely would've qualified. If China had the game before franchising there probably would've been at least 2 chinese teams
The evidence you have presented doesn't fully demonstrate that Chinese region can be seen as the BEST, but it does point to its rather equal competitiveness with the others <--- ONLY SO FAR (and not quite fully yet.)
To draw a final conclusion on Chinese region's equal competitiveness to the rest, however, it would be necessary to wait until the tournament concludes!!! In case, that one of the Chinese teams will manage to win the tournament, you could then claim that Chinese region has exceeded all of the expectations, however, it will still be insufficient to conclude on its BEST status across the world --> but strictly on preparedness and strength of that particular winning team, and even then, as a temporary status ONLY - until next time.
Your BIAS, on the other hand, shows that you are not entirely prepared for the presentation you are conducting. And that is very obvious from what you have presented.
Grade: BIASED asF, kid!
