Yeah but aren't you one of those hardcore players?

In recent accomplishment news, I got Blu to 19. It's really fun. I can either tank or DD with ease, but no one really is interested in a Blu tank. I want to see if I can try to solo some. I hear Korokola Tunnel is a good place. Is that true? I'm going to go there anyway to try to get a Nadrs for level 24.
