I will definitely see what you are getting at, but don't give up on guilds. Notably in guilds in which you raid regularly I found that friendships grow fast. Those are obviously the guilds you'll have to look for yourself, instead of being auto-invited. But yeah, outside of guilds like such it can be hard to find classic wow gold players that give you a second thought when you aren't helpful to them.
Man as a new player I dont know how people may enjoy WOW Classic. I got a sub to play that doesnt play games. We'd like 20 dungeons so far and he had been kicked two times and one time somebody tried to kick the healer for"healer clueless"(luckly for him, me and my friend voted no and that he didnt get kicked, we finished the dungeon without any wipes).they dont say what it is you're doing wrong, they dont say anything, they just vote kick imediatly. The shitty part about this is that people kicked are punished using a deserter penalty.
Nobody speaks at all in the cheap wow classic gold dungeons as well, I had a run once I asked some question, nobody answered, the only interaction in a dungeon so much was someone raging. So yeah WOW Classic is fun if you do planet content but once you get into the multiplayer part it can be pretty frustrating at times. You casuals need to know one thing. You are there, together. They are not your friends or anything. Thats how it is.
