Even though I did make some suggestions, or at least I think the idea should be that Expert Matching should somehow test both your abilities as a teamplayer, and just make sure you reach a certain amount of damage within a certain time, rather than placing you in solo missions that require skills that exceed those actually needed to do the content you would be queing for, I don't really actually want Expert Matchmaking to exist, maybe some better matchmaking system but I just don't think the general idea of Expert Matchmaking is really very good.
I think Expert Matchmaking in it's current form, would just give credence to some toxic elitists that exist in this game, by giving them another thing they can brag about and judge other players because of. They will feel like they were right to judge people because their gear does a tiny bit less damage than they want, because of this and continue to mistreat them. I only encountered this once myself so far, but I've heard other people mention it happen often to them and I feel like it would become more common if this was added.
I feel like as long as a boss only UQ is finished within 30 minutes, that there's really no reason to complain about anyone's performance (usually they're done in 25 at minutes at the absolute max anyway, and of course I'd prefer if they finished it faster but it's no big deal to me if it's not), as long as they were actually doing something, and fulfilling their role if they have one. As long as they're actually contributing to the battle and not literally just doing nothing, or eating through everyone's moon atomizers then you really shouldn't be too bothered about them, and stop watching everyone's DPS constantly like a hawk.
I get that they should be doing a certain DPS, but I feel like for some people the minimum DPS they think everyone should be doing is higher than what is actually necessary to clear content (and some classes do damage differently anyway, some do a lot of hits with lower damage in a short time, some do a moderate amount of damage at all times, and others do a lot of damage at certain intervals of time). So looking at people's DPS doesn't always work either as you have to understand which class you're looking at too before you judge the damage.
I feel like some people just forget that in an mmorpg, you're supposed to work as a team, not judge anyone that doesn't fit your exact perfect dps.
