What have you done is "Optimization" of your existing features (adding infinite HP on CB, improving arena reward, diversified tournament reward by adding artifacts as reward as well). There is no new content or features in the game.
Nobody call this an updates.
People in the comments are correct. This should be included within week's. Update rather than took several months.
If you find champion that's racking your business you will fix it within day like you did with Seer champion when she got released in one of your updates.
But to make CB unkillable took you more than one year to make. This just shows how much you care about your player's heart and needs.
You already understand what players wanted with level 100 cap request. "High ENERGY CAPS" . You could have just made 130 -> 150 or reduce the time its takes to recharge energy. Do you know you just mocked thier request with this update.
Unkillable CB: It should have existed sonce the start of game. Shouldn't have been introduced this late by saying now strong Clans kill them in hour. You forgot that this game is played by all players in different countries. Which means different time zones. Not everyone could hit CB soon after reset. So yeah CB getting killed within 6 Hr was a problem too for an average Clans. They couldn't wait for another key to get recharged.
You have just optimized your old features in the name of updates. Probably because your business is blooming without needing any new TRUE updates. This will only help you prolong your business.
Certainly old players have left waiting for new content as we see alot in every clan and on YouTube. Because new players have replaced them without any need of new content. Since for new players all the content is new.
This game currently going through at its best phase now. Its the same for every game. Certainly in future you will reach a point where you would need to release new content which you have been talking about since last year.
You know what could you have done? Replacing old features with new one like changing Spider, Ice goldem and dragons with new features. Redistributing reward system in those new features. You see? Game is still same and all the champion and thier skills are same but there is new content for everyone old and new.
Now i know with above suggestions you would say. What about its justify old and upcoming players. But what about players who have just started to show results in those dungeons?. I already have 2-3 suggestions for making that transition successful. We both can be creative with ideas to make justice with everyone. We are Fully capable of that. But the real question is do we really want to? Cause it would be too much work and man hours for that.
You are finding easy money.
Make no mistake. You don't care about players. Or you would have justified with your updates for old players.
