Yeah, I was thinking that myself, but they are currently shown as “unavailable” so I’m betting they will change stuff around still. If the patterns hold, after nearly maxing 10 troops for 7*, it takes four more fully maxed troops to get a measly 150 gold per day, then five more nearly maxed troops on top of that for triple tribute chance - more total fully maxed troops that needed for 5*.
Given current release schedule, that would also be at least six months, or more, to be able to attain the 150 gold per day star, and around a full year, maybe more, where the highest available star in every single kingdom gave 150 gold per day. I’m all for long term, but that would be a pretty big time gap where one of the ultimate goals in the game gave a pitiful reward in return across the board. I highly doubt (and certainly hope) that will not be the case.
There is this tidbit:
But it could be possible he had 8 and 9 star mixed up, or things have chanced since then.
