“Demacia Rising,” I've already used up my Silver Shields in Chapter 5. Do think I'll be able to get reward banner before event ends?

It looks like the event will continue until Patch 26.08 ends. I did a quick calculation: Patch 26.08 is set to launch on April 29, so with 24 days remaining, daily play will yield 12,000 Silver Shields, and with 3 weekly updates left, that brings the total to 17,250.

It looks like we can expect to earn about 30,000 Silver Shields by the end of the event. With 30,000, we’re currently in Chapter 5, do think that will be enough to unlock all achievements from here on out?
