The bell system was good before; it gave everyone an advantage, with the bell user getting slightly more but not an insurmountable one. It was also time-gated (income buff rather than instant lump) which puts a cap on it. This was the right idea as it added a community competition/collaboration element, rather than introducing a rift between patreon subs and everyone else.
So, instead of using time warps, expand the bell system instead. Make them all different color bells which buff different stats in different proportions. The ambrosia warp could be changed to the 'red bell' which buffs luck and bb to a higher percentage and cubes to less (or none). Add a blue bell that buffs quarks, the yellow 3D cube/asc speed one, a green octeract one, a balanced white one (the original bell).
Can even add a chaotic one that randomly changes color every few minutes and lets people benefit from all the types of buffs during the rainbow happy hour with active play/management. This adds another advantage for the person who uses the bell in that they get to choose which stats get focused for the buff. Different colors could be allowed to stack, or they'd enter a queue instead and change color at the end of each one's timer.
For added shenanigans/social experimentation, put them all on a single shared timer, and if someone purchases a different color bell while one is active, the bell's color just gets overwritten and adds one hour to the timer. Spiteful color wars ensue, like in America. Hits all the synergistic bases.
