Based on the abilities, we can already deduce which are PvP (The ones with Leech/Stun/Root/Silence/Slow/etc), and which are PvE (DPS CD's, Tank Shields, Ramps, Etc), and which are M+ (Cleaves, mostly), as evidenced by playing the game for a decade+ and knowing that you cannot stun/silence/slow bosses.
We also know how important it is to be doing all 3 forms of content at the highest level possible as evidenced by Legion/BFA. Artifact/Azerite Power grind (PvP/PvE), Essence Grind (PvP/PvE).
So taking all that into consideration, I'd say the community can make a VERY solid assumption on the gameplay weight of some of these abilities, even without numbers being assigned to them yet.
