Hey Bro
1. No matter you make any kind of changes to rules/goals, those who are willing of Pay will ALWAYS have advantage over the freebees. Bro you need to grow up - Life itself is NOT fair. Right from the moment you make your cry (at birth) - you have different privileges - A child born in millionaire family to a child born in slums, life has decided many things for you. You need to realize this and accept that fact that there can never be a FAIR game when money is involved or even when money is not involved - Only thing you can get is that a game giving you close enough opportunity to compete with others.
Bro! focus on Enjoyment you get from playing this game and do not focus merely on results - while results surely is important, so you need to make a calculation on what resources you have (items/girls cards/quest goals/your play Time) and how to get best result out of it. Let me tell you that you can get Daily ranking reward Pack every time at least once in game event , even if you are not spending money. How to do this - you need to figure out yourself.
2. New Girls and Toys. Yes as Pussy boat is cancelled you do need an event where you can get them. Pit or whatever new event development team is working on, it has taken considerably long time. So a new event should really be there.
3. World Bosses. This is a flawed event - just accept this fact and move on. Only target for you should be be to focus on leveling up "key girl cards" that you have to get from other events/Packs.
