What is the level of toxicity of the community for somebody who want to try the game in 2017 ?
Is it mic or text chat, i think i can endure more easily textual toxicity.
Depends what region you are in and your skill level. CIS, SEA and SA are notoriously difficult to crack without going crazy. Then again they all play on US East.
If you know your way around a MOBA/RTS type game you should be ok.
But it's at least a 100-1000 hour barrier to entry to feeling comfortable in knowing what you are doing.
If you are a female I would recommend not using mic.
I think new players are text and voice muted until level 20 anyway. So you can listen and learn for the first 20 hours or so.
Supposedly they are matching new players with highly rated/well-mannered veterans, but I'm not sure how long that will last.
