I have decided to make a full stop playing Raid Shadow Legends. I have played this for one year from October 2019 till October 2020. I believe I have more or less understood the game mechanics. This was as far as I could go before hitting the wall.
Having played several mobile games, the endless upgrading sure did take its toll. And Raid Shadow Legend was really the worst of the lot that I have tried in terms of the number of hours I needed to put in to make any gains at the higher rank.
