Originally I had thought it was worse than 0 bars because if I waited a couple of seconds they stopped flashing and went blank, but today for the first time I accidentally connected to one and it turned out it was full green and the connection was great.
Was that a fluke or is flashing green actually the best?
I believe flashing green just means your game isn’t immediately sure how good the connection is. Basically, it’s going to be sort of random if you pick a flashing one; some of them will be good, some of them will be yellow, others will be really bad.
I think it makes sense that the majority of them are bad - your game can’t tell right away if they don’t get a ping response right away, which, more often than not, means a bad connection. You can occasionally get lucky though, I think.
I usually get lucky with those. Either I can connect and it’s green or at least yellow or I get cannot connect at all. It’s pretty rare that I try a flashing green icon and get someone with red/orange (though it does happen)
