A Bit of Advice
So I'm not an end-game player i.e. I have not completed Act 5. I only have four 5-stars which are Guillotine, Captain America (Crappy Classic), SIM, and Howard the Dumbf*ck. Guillotine already r3, but who should I be taking to rank 2? I have a few resources to burn, so which other would should I take up to r2?
