Not all weapon upgrades for a given weapon comes without a risk and it would be nice if we had the option to deactivate whichever weapon upgrade we do like to for a given weapon.
An example: I did not know how the explosion worked for my Divine Protector or other weapons before I had upgraded it fully. It first create the gems, then it explode before the gems has matched. Today I ran a few tests at 0,25 ingame speed, and the explosion was able to destroy a 4 match aka extra turn for me.
I just hope we can have an option to deactivate whichever weapon upgrade we would like to. It would be nice.
