I am writing this because i want the developer/IT team to notice this
1. What age age group of players are you targeting?
As it is "dirty" league i am assuming you are targeting age>18 years. Then showing boobies/nude 2d art pics just doesn't cut into +18 for me. Instead of focusing on adding *dirty* animations to event(s) and add some color/fun to events, the team is focusing on something which is least requirement for such a game.
2. What is purpose - popularity or Money or both?
I am sorry to say, but hurting the large player base (new players/players that do not pay) is never a good thing for popularity. You can just make the game exclusive for players who pay, if your team is least bothered with freebee players.
For any game to be popular, it atleast has to be *fun*. Last update just killed the fun for me. Even at the start of fight, i pretty sure know that i am going to win the fight BUT still i have to WASTE mins into it to get the result. Are you trying to build a tactical RPG kind of stuff instead of fun gem combination style game?.
3. The reason listed for such change (= balance) isn't palatable to me. According to me, such change is intended so that the PVsbot fight becomes challenging for top players who are winning every fight (<5% of total players), BUT it has ruined the game for rest of player base (90 -95% of player base). You can add a survey to confirm this with players.
