To me this meta is yet to be defined, because they did nerfd vanar consecutivelly ( like happen to lyonar years ago), but now maybe Magmar e Songhai have the most unchanged abusive things ( althoug they slaughtered katara before bring it back).
I mentioned the cards for simple reason. They need to decide wich direction take the game as said. If its a card game were the board is an extra or a board game, in wich case its suppose to be slower and more focused on bulid up. To me what i hate about it today is an obssession with tempo/speed. you goatta play aggro an “cant be answered” cards because everithing is removed too fast. And the fast removal is necessary to answer overpoered cards typed “answer or die” like excelsius or nosh-rak. Curiously those very cards became useless because they’re always answered or played around so the meta is all about what can’t be answered or is hard to play around like shinzar’horn or Zendo.
This make decks a freak race of aggro and removal and that reduces the game options with lots of fun things becaming unplayable because they’re not fast or reliable enough (battle pets, variax,and in the Emp meta arcanysts).
In a board game teams have minions with way lower damage and higher life so they stay in the boar longer and the tatical part is enfasized, but obviously there are no minions or spells thet win the game instantly so theres no need for desperate fast removal. But its no longer a direction to be taken. Its a TCC, aimed to be competitive and became not fun or to competitive is probably its destiny. But they really have not figured out how to market it because they dont know how to please their fanbase and pursuit a new one at the same time.
It is going to be like major card games with this competitive aggro/removal psycosis and search for super combos and everybody playing the same decks ( wich in fact limits the options making roughly half the colletions unplayable even for fun). Or they reshape lots of the abusive cards to make the game slower.
For both scenarios make a unranked game seems to work better because it makes possible to play lots of things in a less competitive apex scenario.
Other option would be enable a ELO system, were you can play decks with cost limit, wich is usually popular with new players and makes competitive but lesse reliable on budget and creates a scenario with lesser advantages to veteran players.
