Quantum's Take
Captain Cold has seen a complete 180 in the game, from being considered one of the worst champions to one of the most important for non-spenders looking to improve their Combat Cycle scores. His ultimate functions much the same as Cyborg's, but only for single-target. So there are some clear limitations to the kit, but ever since the developers fixed his ultimate, we've seen him added to some interested Physical DMG lineups and he has finally found his niche spot in the meta.
