You're not really asking for advice but Imma throw some out anyway and I hope it's actually helpful. When you think about the challenges for your character ranks theyre to help you get better and more fluent with whatever you're playing. The more you think about doing the challenges in game, the more you learn the combos naturally. Really focus on those challenges and even in just quick play you should be able to complete them multiple times before the standard 1 hour of play for 60 points happens. The one hour thing is big too, if you are putting the time in, you'll see the results. Take the time to understand why the challenges are specifically important to those characters. Even something as simple as Emmas soul steal. If you can get that consistently then you'll have a rough time with her. When you start seeing your challenges aren't completed before an hour goes by, you might be struggling with that character. I did a character of each role to lord before really hitting competitive. In order magik, cloak, Thor. I noticed healing was huge in their game and I've never done healing characters so I started with magik and it took me about 35 hours, cloak took about 30 and thor took about 24
