How would an optional, official parser be toxic?

If the gatekeeper has several mechanics from the following raid tier, then you're actually preparing people for them ahead of time, because if you can execute them on the gatekeeper, you can execute them on the raids themselves.

then why do you need the gatekeeper? Generally it has to be a lesser or different check, or then the fight is just a formality. It also has to be hard n itself. I also don't think knowledge transfers over as much, each fight will always be unique even if the base mechanics are borrowed.

It's no big deal for the person being carried. After all, they're not the ones making an effort to compensate for the person not giving their all in the fight. If such a person was in one of those statics that prioritize loot based on necessity and performance, it would take a while till that person got ahold of a gear piece

You compensate for each other. You don't view people like that, you invest in them. If you view them as burdens, well guess what, one day its your turn to be viewed as one because you suck at a particular fight this time, or your job is unoptimal, or new guy is better than you.

You also have people complaining that a MSQ fight easier than most dungeon bosses is too hard, so it's not like it's just one side at fault here. Plus that's on SE to fix, not people to endure.

The people who complain about those legitimately have problems with the game that story fights are all they can do. And the complaint is about unexpected difficulty. And the sheer griping about others who are lesser skilled gets old considering how little they affect you.
