Since I completed it, I'm like "Screw the arcade! I can just take the mission "The Gauntlet" and just get my crowns and heat from there repeatably". I can easily level up items and easily get a good amount of crowns (around 4-5k per run). Oh...and the heat is a good amount...lvling up two lvl 8 5star items up to half.
Now if you excuse me...I'm gonna go raid on it.
Would this be... before the cr/heat nerf, or after?
