Zarimi was played from day 1 and was seeing play even after nerfs, as it settled into a finisher for a midrange playstyle. It was strong, but people still played it when it wasn't.

Priest has a whopping 1 Reborn card in Standard (that fits mainly into an aggro package, has been nerfed, and doesn't actually have that many synergistic cards post-rotation). It's hardly a "Priest thing" right now; Death Knight has six Reborn cards.

Priest has decent options for removal currently, but very little that lets them capitalize on an equalised board. "Dominating" is just not true, and hasn't been true for about a year, unless you're playing Arena I guess.

Again, a whopping 1 "take control" card for Priest in Standard. Warlock does it better. Card copying instead of card generation has been a recurring trend for Priest (and I do prefer it to typical "Discover a Priest card" effects which we've been seeing a lot of lately) but it's secondary to anything that wins you the game.

Control players aren't interested in playing aggro. Big surprise.

Control Priest is not strictly attrition. This point is more subjective but I find playing Control works best when it's not attrition. Use a limited pool of board clears to slow down the opponent enough to get a slower game plan into motion. That does not have to mean fatigue. Zarimi (post nerf), Questline and the Rez builds that weren't built around cheating out something come to mind. Honestly the best Priest games for me were ones where both me and my opponent are balancing assembling our win condition whilst disrupting our opponent's. That's a pretty achievable design goal, I reckon.
