Thank you! I'm quite happy with the balance, my testers have all independently come to very different metas, so there are can be a few "S tier" upgrades depending on how you're building.
oh for sure, i wasnt trying to say it like criticism/imbalance, i just really like the move speed upgrade. i love when metas arent implicitly designed but discovered by the players, i still dont even know what the best strategy for my game is lol
