Cosmic Quandary

neglass7

I’ve finally worked my way to having two 4/55 5*s (Blade and Magik both unawakened) and I will soon have the ability to take Venom to 4/55 as well. However, I pulled a Corvus after him that is sitting at 2/35 that I could take to 3/45 instead. Should I put the resources into Venom now for another rank 4? Or should I be patient and put them to Corvus and save resources to take him to rank 4 later?

For context, I finally went for Uncollected, and will be looking to explore 5.2 and go further into Act 5, as well as complete RttL and RoL.
