What would I like to see more of?
I want more maps like Lazy River and Young-Hee's Revenge. Dizzy Dash could have been one of these, but the mechanics are completely broken for it. For example, you can't jump from the first small spinning bush to the first large spinning bush on red, but you can jump from the second small spinning bush to the second large spinning bush on red. Why?
I want to see characters and item boxes rebalanced. For example, Spud and Jackie have similar abilities, but Spud's ability always kills and Jackie's doesn't always kill (although it often does). Why do these have the same % chance? There are also many out-of-the-way item boxes that sometimes give useful items, but often don't, for example, Maze Race. There's a box on a platform by itself just past a boulder spawn, and that box gives dalgona/shoes/pogo/shield, maybe even weapons like dodgeball/bat. If I lose 3-4 seconds going to get it, I don't want to get a shield, I want to get something that's guaranteed to be useful like a dalgona or a shoes or a pogo.
I want to see less, or even no, fireworks. Or at the very least, reduce the stun duration on some of these items. If I'm holding onto a pogo on Lava Leap and get hit by a fireworks, I don't want to spend 5 seconds falling to my death, stunned the entire time, completely unable to use my pogo. Reduce stun durations across the board and let me use defensive items like pogo to recover back to the level.
I want more elimination maps, especially ones that aren't solely bat-focused or snowball-focused. What I want to avoid is maps where Spud/Ace/Jackie are a free win, or Emmi/Raja are a free win, but also where their abilities aren't useless. Towering Inferno is a perfect example (although Emmi/Raja do suffer on this one) because you can get a bat, but it's not focused around bats, but you also can get a dodgeball, or a pogo, or even a shield, and there's valid reasons for all of those items. Dodgeball can mess up someone's trampoline jump and kill them, or push them off one of the flame vents at the end. Bat can obviously kill. Shield can be useful for standing on a flame vent and buying yourself more time in the unofficial kill timer when you make it to the final clockwise race at the bottom. Pogo can do the same. There's also trampolines on this map to let you reposition effectively. It's a great map. It would be nice to have more elimination maps that multiple different character archetypes are good on, and not simply item-specific characters.
I want race maps where there's different routes with similar timings and reasons to take each route. I want characters that interact more with item boxes - maybe a character who always has a chance to get a knife from a box, or always has a chance to get a shoes, etc, something that makes maps more dynamic. I want more customization in terms of costumes - let me put an X or an O patch on my character, or change their hair, or something.
I want larger parties. I want the ability to play certain levels in private games by myself - why can't I practice Lazy River over and over in a private match? I want exact %'s on item abilities. What's the % on Legendary Chance? Who knows. What exactly does Diego's ability do? Who knows.
