I find it amusing all the people having a cry about this, if you're so trash you don't have 8+ legendaries in your main spec now (If you're good you'd have all your main spec legendaries) you're not good enough to be doing content that requires the legendaries. So what does it matter.
Ofc if you play casually, you aren't trash, that's just your playstyle, but those in that scenario really don't need bis legendaries.

You don't need to be lucky to have 10 legendaries by now, you just need to do the right content. And by good, I moreso meant players who are doing difficult content, raiders/good pvpers etc.
