Is there a big difference in regions

I wanted to know if there was a big region deference in skill level like would a low tier 2 na team do good in japan challengers or latam or something

i dont think prx something is a region but ok

best NA tier 2 team got dogwalked by emea tier 4 nobodies
enough said

probably mid table at least, some of the tier 2 japanese teams are just there to develop talent

Probably not much a difference, maybe middle of pack like some others said but I'd say alot of tier2 teams also construct rosters differently. Some are talent developers, some are collegiate, some are academy, etc.

basically APAC is about 5 times better than any other region, and the others are pretty much the same, its just that nobody is on the level of apac teams

a mid NA t2 player would be pretty good in japan, and a bit better than he is in NA in latam I think. Depends on his role tho
