How would an optional, official parser be toxic?

But, I suppose we can't have the game tell people they need to get good to participate...

There's actually a serious problem with this.

Let's say its a new tier. It requires you to beat a gatekeeping battle that's harder than SSS (because a lot of people think the dummies aren't a good measure. So maybe a mock battle or something.)

One guy beats it on day one, and gets to work on the tier because he's a good player who already raids.

One guy can't beat it at all, and stops raiding.

One guy takes a week to beat it.

The problem though is the last guy is going to be delayed enough that it might matter for progression. The weaker or newer they are, the harder it will be to find people. I mean, the people who beat it day one will be ahead of them and less likely to get newbies because finishing later my be a sign that you had issues with the dps check. It might be more of a discouragement than people think. It's add more teeth to the "two week problem," that it's harder to progress in stuff 2 weeks after a patch.
