Old meme or you really living in a barrel?
Asmongold may soon become the most popular FFXIV streamer ever, so this is a pretty good suggestion.
I've seen a few Asmon vids on youtube and I quite liked them, but my knowledge of him is pretty vague to be honest.
Just as a general thing though, if someone is toxic and their presence would make the game worse then welcoming them might be a nice thing to do, but it would be bad for the game and the people that currently enjoy it. Being nice is not the same as being good, and if you feel a course of action will lead to a greater good then you should be prepared to sacrifice being nice to achieve it.
A lot of people just don't care about streamers.
He's not even playing yet. lol
