Who are your most used champs and who of those you don't use, who would you use more if awakened or benefit so much, that you'd get more use from them?
The question is always which champ benefits more from the dupe and which less. For example, the torch has practically no advantage from the dupe, except that you might be able to launch the ability skin more often. But based on the individual match you have practically no advantage. So even though the torch is a really strong champ, I wouldn't awaken it first. Based on that I'd say Nick or Kingpin and Scorpion.
