I used to be bummed whenever I saw an event that had nodes requiring a specific character. I just knew I was missing out on those extra points that would help boost me to the upper tiers!
However, I’ve managed to still place fairly decently in my brackets, and have since built up a reasonably varied roster (kinda kicking myself for selling some covers early on, not realizing the synergistic opportunities when certain characters are teamed, but live and learn).
Now that I have many of these characters, though, when I see those extra nodes and discover that I have the necessary character, I find myself thinking “Aw, shit, more nodes to grind.”
Yeah, history has shown that only rare 3/4* characters will ever be Essential for events. Currently, that’s Daken. Sentry and maybe Nick Fury will be next.
Cap** was required once in the Brotherhood event. It was weird but we didn’t have lazyCap then
IW was required once even earlier and never since, and I hope she never will be.
