I would say it is still useful. 6 FPS plus attack boost in 16 square is still competitive with all the new event building. That’s why it’s still got bid at a relative high price. I’m still looking for 3 more upgrades to max it out, but I’m not willing to pay that much though. I bought one for about 20k, which i think is fair. But sometimes I saw it in the 100k which is way too much. Last I heard, it will be available in the antique dealer soon as a direct buy, but I bet it’s gonna be pretty expensive.
