I’d wait for a seasonal event especially because they offer a total 2.5% chance of of 5* per summon, while a basic epic summon gives only a 1.5% chance of a 5*.
I’m saving mine for summer. Summer heroes cut healing away, which is very helpful for field aid wars. AND I’m waiting until the July part of summer, because June’s monthly hero looks like garbage right now. I’m hoping July’s will be better.
In further analysis–Springvale had only one 5* before. It got 2 more, so now it has 3. The Summer event currently has 2 5* heroes.I’m guessing it may get 1 more, maybe 2. Halloween only has one, so it should get 2 more at least. Christmas also has 2, so I’m thinking 1-2 more.
Newer heroes tend to have a higher chance of being really awesome. Therefore, if you’re really patient and if you don’t care about field aid as much as I do, I’d think Halloween would be your best bet for an awesome 5* if you’re looking that direction. Planning for 4* pulls might be in your best interests at this point, though, and Buddy from Christmas is one of the best 4* around. Now you’ve heard from my real long-term scheming side.
