Stop being spastic.
The ring loss works like Sonic 1/2/3 because it literally was meant to emulate those games. Partial ring loss would be inaccurate to what people expect from something inspired by the old Sonic games, and we want to be faithful to that.
Setting aside that, the game is balanced around this mechanic for two reasons.
1. There are lots of shields now. Multiplayer starts you off with a shield, Single Player has magnetic, elemental, and force shields all over the levels, and they're designed to help you keep your rings. You can get hit a few times and not lose your rings because of this.
2. This game is designed around you being able to dodge everything. The only excuse for you to lose your rings is that you were not good enough. The ring emblems are designed to test your skill, so you shouldn't get hit. The vanilla game rewards you for every 100 rings you get, and partial ring loss would make gaining 1ups too easy. I can get like 20-30 lives in a no-save run, but without rings this drops to 10 and under.
