how fluent would you need to be give/receive comms

wondering because aspas was wanting to go to pacific, so how fluent would someone need to be to give or receive comms in another language? it doesn't seem that hard especially for japanese where many of the locations on the map are simply katakana versions of the english words (although portuguese is his first language so idk how useful that is for a brazilian). someone said N3-N2 but seems kind of overkill. i'm not sure how complex IGL calls get either so maybe that should be taken into consideration. i'd think he'd just need to learn a few niche calls and he'd be good for the most part

There's a reason why only 2 Russians in vcj ever won the title across 4 years of valorant's history.. Hell, they are the only English speaking roster ( disgrace) to ever won vcj
