Annual Pro+ subscriber here, mostly using it as a fallback when my Claude Max plan hits limits. The request-based pricing was genuinely the appeal, I could spill over from Max into Copilot without thinking about token costs. Going from 3x to 27x on Opus on annual plans is rough. The newer reasoning models with variable thinking budgets probably made per-request pricing untenable in the long run, but the way this lands on existing annual subscribers feels harsh. Going to look into the prorated refund.
