Well, good news - the brief amount of your roster you've shown us has already been enough to conclude you're set. Ninja, Kimi, Tayrel, Magnarr, Fenax, and Giscard are all worth taking to 60.
I'd probably start with Kimi and Ninja.
Thank you so much. Now I know where to start.. if you have time please just leave any suggestions for me. I would really appreciate it. Thank you again
If I were you I would focus on Clan boss, Campaign, and as much of the challenges as you can do if youre able to play frequently.
The challenges progress in difficulty and a lot have you farming easy campaign stages 1 and 2.. you dont want to have to do this after youre 180 days in and have finished nightmare campaign.. trust me, its a headache.
As Kram said from the picture you have some really good champs. Ninja is useable everywhere, godtier for clanboss. Giscard is great for team protection, Tayrel, who I would say is S tier epic, but so many awesome epics have been released since raid's beginnings its hard to tell, has really good multipliers and DEF champs are great for newer players.
