While I do understand that there’s no need of Clock Towers cause of unlimited gems but I still feel it would be cool to be accurate to the original game. That way your bases would be 100% accurate and you can practise your attacks accurately as well. Please look into this and consider adding the Clock Tower.
Also as someone else said, letting X-Bow and Inferno Tower keep their loading costs is fine I think albeit pointless. Just makes you feel you playing are the original game indeed but with extra gems
