lack of flurry is manageable now, against control and midrange decks where your single target removals are more than good enough and generally you are the aggressor anyway. You could beat shaman before by flurry on feral spirits and their other stuff and out tempo them out of the game and there was the outracing potential in flurry too. Now it's just almost impossible. Other classes in next set could become a problem too, I don't think the concerns over the overnerf were wrong. Right now fok and thalnos are good enough for zoo and similar and against control you don't need more than that, patron looks like it's not going to be popular. There is always skulker if you want an extra clear but it doesn't do enough. 3 damage is the threshold you want to hit for it to be a real board swing. It's only real impact is against zoo again and it's rotating out next set.
Even when that future meta happens, I don't think you play flurry still, it's just extremely bad. 4+2+1 mana, losing your weapon in the process to do a worse flamestrike? it's just not going to provide a swing, it's an stall maybe, a very expensive one. hell, prep vanish is maybe better even if you want to stall. I think at some point they should print a new aoe spell that is not tied to your weapon.
Something like 6 mana, combo: deal 2 damage to all enemy minions for every card you played this turn.
