Still asking. Classic or Classic & Retail - updated

This is an example of why I asked:

We discuss LDF in Wrath, and then Terres as an argument, or counter-argument spouts Mytic and Retail examples. I just don’t get it, I stop reading, and instead start wondering if I’m the only one not understanding what she says.

This is the reason, I asked. Not anything else. no petition for Classic only subs, no hidden agenda whatsoever. Plain curiosity.

And Furia:

No, I can’t /don’t. Please explain. I have not played Retail since BfA (Fall of '18) and even well before this I played mostly IronMan Challenge or did professions on my main.
