This is just a bad idea in every way. Learn to take a loss, it feelsbadman i know. There's only one positive to this and a bag full of negatives. Just think about it for a minute and don't let your emotions rule you and you'll see why such a mechanic will never be implemented. And competitive HS isn't an argument since they are not in a queue waiting for a match etc. it's a whole different play environment.
The class ban will never happen, and do you know why? Because the next day after the class ban is implemented, you'll have Zeddy Hearthstone leading his 17k mouth breathers in a crusade to have ten new balance discussions, one for each "class banned" meta.
And funnily enough, they would be right to do so. If such a stupid idea was to be implemented, it would create eleven sub metas (including the one where people don't choose to ban), all of which would have an expectation of balance. Good luck with that.
They ban classes in tournaments, the most competitive form of play.
Tournaments are a completely different environment to ladder. Each player has a predetermined number of decks to use in a “best of x” setting. Strategies are designed with the ban in mind and crucially, the players still have to actually face each other. If two players meet in a tournament, they can’t be like “nah don’t fancy that” and ban the other player entirely, which is what a ban system in a bo1 setting effectively achieves.
Implementing bans in a solo queue system simply means you cannot face players who are using your banned deck at all, which further reinforces that you will have to use the best deck to climb, since players using it will ban its counter, while everyone playing lower tier decks will ban it out, and leave the mirror match the only option to ascend the ranks. It will destroy diversity and meta evolution at top legend, where most of the innovation occurs.
Additionally the only way to implement this would be a class ban, which would absolutely suck. Using myself as an example here, I laddered bronze 10 to legend this month exclusively with Control/Fatigue Shaman. This deck isn’t keeping anyone up at night but I would be banned out by half the server because evolve Shaman is out there stealing away people’s kids and wives on a daily basis, meaning I would probably be stuck facing nothing but Evolve Shamans and Aggro Demon Hunters for my whole legend grind.
I could see this maybe being allowed for casual mode, or bronze and silver divisions only on ladder, but it still takes away more from the experience than it adds.
Ah. This old complaint again. It took a bit longer to come around this expansion, but here we are again. As countless others have mentioned, countless times before, this is a terrible idea and not something Blizzard will ever be likely to want to implement since it creates a huge opportunity for abuse of the game mechanics. And as someone absolutely correctly stated earlier in this very thread, it would also create infuriating little pocket-metas (loads of them in fact), which would need a huge amount of micro-balancing and would not serve to improve the game in the slightest. It is nothing more than the usual complaint that someone doesn't like the fact that a particular class stomps on their little homebrew deck and they refuse to adapt to the meta rather than demanding Blizzard adapt the meta to them.
