Every expansion has a few OP aggro cards, it was inevitable this would eventually lead to a situation in wild that was way out of control. This is why the best fromats in the game for me overall are Arena, Battlegrounds and Standard. Do I keep my wild cards? Yes - it's fun to keep the collection and I'll always play the tavern brawls.
Speaking of which - the current tavern brawl, where you pay health for spells is what wild feels like for me, just sped up slightly - a race to see who can pull the most unineractive, unfair, not-designed-for-a-30hp-game BS play first. There is very little strategy, it's all draw RNG. WIld wasn't always like this - it had it's moment in the sun, when the game was less saturated with broken cards and it was the best constructed mode in the game, but that time has long since passed and it's not coming back. These days its good for staying around bronze chicken rank, completing quests and playing stupid meme/tribe decks that you built yourself for fun and know are no good at any remotely serious level of play.
