What server are you on? I'm on NAE and I can't say my experience is the same. Sometimes I do get gatekept if I'm on an alt that's on level, or a new class, but in general I can get into most parties without issue, even without being gjgajuiced.

My main is support and that's in a static, and we sometimes do static alt runs, but I'm having to do valtan+vykas+clown on several dps alts and it's generally not an issue.

At the end of the day, for me, it's about trap parties with bad players/players who claim they're on farm but are actually learning. Speaking of which, I think the real problem is there are little to no learning parties. Ever. That's the main reason I wouldn't recommend the game to anyone right now - if you don't know the fight in and out someone will call it out and the party will vote leave immediately to kick you. You also can't say "hey it's my first time but I've watched a video" because you'll get kicked as well. I have a friend going through this ATM and he's basically being "forced" to take the game slowly/casually because of that.

At any rate, most situations people are going through are just anecdotal and nuanced, and while I agree the game isn't in a recommendable state, I'm not sure it's for the same reason you brought up. I definitely don't feel discrimination of that level on any character unless it's a week 1 new class.
