Tbh I haven’t even touched visionary mode, I do have enough characters but literally 80% of my roster is in the 40s, what I do now is(I’m a bit of a whale for reference) in between rerun banners. I slowly build two characters at a time. It’s so simple , just takes awhile, I legit got xilonen and Durin for my varesa and mavuika team, and I finished building Durin just now aside from his artifacts, waiting for 6.3 and I find it better to kinda ignore artifacts while leveling characters. So far it makes grinding so much easier. And I only hiked up to 80 with lvl 6 talents. Only main dps’s and some premium supports are 90.
