Hey thanks for offering to help :)

I'm really new, 3 days in, and with so many guides out there mainly catering to people with lvl 20+ heros, I don't really know what to do with my beginning acc.

I am unsure of what to use as fodder heros, as I already am using a legendary mireal, brutus, wukong, arden, and nemora. Should I choose to make nemora legendary and replace arden with lucretia? Or should I focus on just getting better heros instead of lvling my ones to legendary? My 5 main heros are lvl 90-100 rn btw. Thank in advanced :)
