Act 5 exploration or concentrate on other content for progression
I am currently trying to progress as fast as I can. I'm trying to explore act 5 100℅. Currently 61℅ completed overall. But some paths in 5.4 are giving me a hard time. Being a free-to-play player I do not prefer spending units for revives. Should I be focusing on some alternative content that can help me build a decent 5 star roster?
