Advice to progress on cb and dragon team
Hello, I'm kinda wondering how to progress mostly at cb and towards dragon 20. At first, I started to lvl up legendary assuming they're stronger than epic's most of the time. At this point in the game I'm unable to book them (only have few books for lego) and noticed that there is a big downtime in buff/debuff witch I think hurts in cb and dragon. Checking some guides, it seems that I do have some champs with potential in cb, but I struggle a bit on what witch champ to work on. Like geomancer, vogoth, rearguard sergeant, fayne, veteran, deliana(maybe). I feel there are so many options and struggle to notice what would help my team out.
What would be a good option to start on?
Here is rooster till so far:
Currently this is my cb team setup:
Skullcrusher, keal, ninja , riho and drokgul (also use this for dragon).
Btw, Is it better to take on epic and fully book then before legendary?
Best regards
