I’ve been fighting the same feeling for a few months now @Taisiakat. I found that the grind of the game was getting boring and the meta of facing the same killer teams over and over was taking all the fun out of the game. I am an end game player now and was playing hard each week to amass as much gold and trophies for my guild as I could. I held on because of the proposed guild changes that were still in the future at the time.
I decided to set goals to give me a reason to play. My first goal was getting all my kingdoms to 5 stars since they were all already at level 10. That meant completing my deck so there was soul farming for levels and doing challenges over and over since this was before Explore mode. Once this was done it led me to my next goal of traiting everything in my deck.
I had cut way back on my play time as far as pvp went. Instead of getting more than a thousand trophies each week, it fell way down to 600 and rarely went higher. Once I reached that mark I changed over to Explore mode so I could farm traitstones so I could achieve the goal of traiting my entire deck. At the moment I only have Abynissia left to trait.
My next goal is to try and get my complete deck to mythic level. I have approximately 3 dozen troops to ascend. Problem is that this falls into the control of RNG when using keys or gems for opening chests. All I can do is hope I get the cards I need.
Each time the devs bring out a new kingdom it kind of resets these goals because now I have another kingdom to get to the same point as everything else. This gives me something new to do (kind of). Now that the new guild changes are here and they’ve added the legendary tasks it has given me something to strive for again. For the most part.
I really enjoy match 3 games and this is the best one going in my opinion. I may not like some of the things the devs have done in an attempt to make the game better but I’m still going. I still play. You could try setting similar goals if for nothing else but to give you something to achieve so you feel good about doing the grind, fighting the same teams and doing explores over and over in hopes of getting those stones you might need. I know I felt pretty good when I could finally say “I now have a complete deck”.
Keep playing. Try new teams. Change your playtime up (less / more). Find what you enjoy doing in the game and change your focus to that for a while for a bit of a break. Good luck.
