EXP/XP/Experience - As of now, the experience players can gain, caps out at 326,400. Why? The experience players can gain should not cap out at 326,400, however, it should cap out at 10 Million or more. This feature should not be hard to implement. You could implement better rewards for players that have already passed 326,400 EXP, such as a significant amount of coins passing over 300, Prodigy Crates, Bundles of Epic Skins, a legendary skin, loads of credits passing over 70,000, and even a legendary mech or weapon when reaching landmarks such as 1 million. Or just put 'random reward' but the random rewards should all be the same possibility percentage and should not include the normal crates only prodigy and gold crates but in bundles. Also, it should consist of way more a-coins, and blueprints should not be alone, they should come in a package with credits or something else.

Names of mechs - The names of mechs do not make sense based on their ability and features. The slingshot does not seem like a slingshot, more like a kill shot. Change its ability to where, when it dashes, it also dashes right back to its original place after dashing. And make its health and damage a little higher. 

Same with cheetah. It is not fast. Either make it fast or change the name. I'd suggest making it faster since health is not a key feature. If you don't like that idea, then change the name to something more fitting like: Mephitis, Quail, Duck, or Goose. I like mephitis since it's similar to a skunk and leaves behind something unpleasant, and they are not as fast but they can be fast. Also, Mephitis sounds cool.

Also, there is nothing wrong with making silly names, I mean, you could even rename cheetah to DuckDuckGoose, it still would make sense and it's funny.
