Hey, I think I’m doing something wrong because my progress in the new event feels really slow. I keep dropping in the rankings even though I’m logging in frequently and upgrading regularly.

I feel like I must be missing something, or maybe I’m upgrading the wrong things? I’ve been trying to upgrade everything evenly, except for HP.
