Rumbleverse might've been too much like a fighting game for its own good. Learning mastery of mechanics and situations is great. I love it. I am a fighting gamer. I'm not sure how many people are ready for that level of study to support a live service battle royale game, though. There was a whole system of priority levels. No option beat everything. Stronger options were more punishable (besides maybe Super, but that's time limited by meter). Much like a fighting game, there's always going to be tactics that beat newer players very easily until they learn what mistakes they're making. Being able to get into a match and not die near instantly because someone snuck up on me (unless I'm on a really tall building) is a great change to the battle royale format that melee combat offers. Getting lucky wins is far less common than it feels in a standard battle royale. I didn't vibe with the art style at first and it didn't really grow on me that much, but I can't deny that it suits the Looney Tunes style action the game offers.
