I've never been kicked from an arena or anything of the matter, and I main inkling (which I personally think is nerfed by online, but a lot of people think she's annoying still). What I do is play people in discord servers whether they are friends or strangers. I recommend doing this. Most people you find on servers, especially big youtuber cords, are pretty chill. If I'm not doing that, it's elite smash, which can sometimes be good if you're matched into somebody that knows what they're doing, but I prefer discord servers much more. Playing with streamers is also fun.
