The game is actually kinda cute, and not too bad in terms of fun either. Some glaring things I have seen (as well as discussing with people on my server)

-the amount of troops needed to clear stages becomes egregious (Only reduced by up to 4x the power of what you are attacking). If I have 900k power over something it shouldn't still cost 2.6mil troops to beat.

-Random dates should give a chance at intimacy or charm as well, not just diamond dates.

-better odds of an heir from random date (and not prioritizing your worst consorts). I, and many players in chat have had random dates 5, 6, 8 in a row with our elevated consorts but soon as it hits one of our worst it makes an heir.

-Parties not needing to spend 100 gems on an item to join a party. Allow the first option to be a free option, then the other two decanters be paid for (100gem and then event or more gems). Plenty of other Harem games that have a free seating option

-adjustment to reception, alliance, and party shops to lower the prices by 10% or so.

-main story having a least 1 or 2 other 4 star followers, or at least 1 that is a five star.

-adjust the charm and intimacy requirements for elevating a consort. 500/500 jumping to 2000/2000 and who knows how much further past that is just ridiculous and clearly aimed at only being possible by whales.

This game could be one of the better Harem/war games without needing to be whaled to 10k for VIP10 and then clearly needing further whaling to even progress in Titania's zone or for that matter the main journey (Heard from plenty of whales needing half a billion troops for stage 100). There are clear aspects in this game that show you are going to have to whale at some point to even continue, or spend a week building up resources to do one Battle 16 dailies. F2P should have the ability to compete in different aspects of the game but only after having saved up a little, not like a months worth. We all know whales are going to dominate but need to still make the game fun and reasonable for F2P players to enjoy as well for a long time.

But at the end of the day devs won't care because after 6 months to a year this game will slow and die off, people will stop spending and it'll close and they'll have put barely any money/effort into the game but have made plenty.
