In past seasons, a sea fort could reliably get a few levels of renown, even in the 80+ range. Season 9 rolls around and on day one, I knock out a couple sea forts and wind up around level 18 or so. I’m solo, so I’m happy with that.
Three weeks pass and I hop back on, knock out two forts and a skeleton ship and went up one renown level. It was odd so I kept playing and it just felt like it took me forever to go from 18-25, several hours over two sessions. Did something change? Renown slows down for sure, but it shouldn’t be that slow in the teens and 20’s.
