This is what i'm hoping: "ok, 8man duties and primals hard count as high-end level duties. ALSO, we're adding XXXXXXX as high-end".

This is the case. It reads as of 2.2 these instances will count toward the count of 200. Notice it has the leviathan fight, which wasn't in 2.1? I'm sure they'll give tanks retro points for stuff they've cleared before, and now they're saying, additionally these instances will aslo count as of 2.2.
