With these changes candy coated armor needs to be buffed, it’s been powercrept since the times of acropolis armor being the best heavy armor. It used to be gaining 6 def while losing 10 dex. Now however if you add these changes you will get to a point where it’s gaining 2 def while losing 10dex not a good trade off at all. This is even more obvious when back when candy coated was made pets weren’t rampant with lots of healing and there werent many options for def and hp so candy coated armor and exa hp ring together was probably the strongest defensive combo.
I don’t think it has to be buffed too much, it can just not lose as much dex or lose a different stat. I understand that the tiered heavy armor should be the one with a lot of def with no negatives so something else giving you more has to have a drawback but it’s going to be too high a drawback as it is.
