Avenger Carina Challenge manageable with r3 Thor and OGBW?
Finally got them both to sig 200. But I'm wondering how necessary it is to R4 them, or if a 30% green boost active the whole time will be fine. I awakened my 7r1 Hawkeye the other week and already have Iron Man r2 awakened sig 40, so they're good to go. Only other thing is Antman who I have as 7r1 unawakened, otherwise I need to take my 6* to r3. Wondering how necessary that is as well.
Whoever's done this recently, or in a similar boat...how many resources did it cost you?
Thanks!
