I think it is becoming quite clear, more and more people are wanting to leave this game.
It just isn't fun anymore. IT stems from three things as well. Daily PVP grind for incubators. PVP in general with its pay to win Nature. And the seeming threat of a level increase.
You want an incubator to run over night. Prepare to run through 10-20 battles of RNG nightmare.
With deaths coming from being critical Every other turn. Or if not that bad luck, how about them having the literal prefect team to counter your own. IF not that, then having one of several OP dinos.
OR worse case, a mix of all three.
So what used to be a half an hour to get four incubators, becomes an hour long slog, and even then you don't get all four.
On top of it become more pay to win, with people getting access to those NEW op dinos so quickly. It is becoming a nightmare for any free to play person.
This pay to win, nature for PVP. Is honestly why other games died off. Everyone hates micro transactions. You need to look no further than the remake of Star Wars Battle Front 2 for how micro transitions and a pay to win mentality by the maker ruined the game. IT barely survived that.
IF you must have a way of bringing in money. Yes, use skins as a way to earn money, or gain access to coin cash and incubators. But you should never let part of the main grind be directly effected specially when it affects other players gaming experience.
IT shows a lack of understand of your game, and shows yourselves to be extra cheap.
Lastly Level increase. Where to start... Oh yeah. DON'T. Reaching level 30 is already a hard enough climb without adding another 10 levels to that. IF you do it as the game is now, only pay to win players will have a chance of reaching 40, and a number will within the first day. Everyone else will suffer and quit.
Level cap increases, will require an entire rework of the system.
To be honest it needs it anyway.
