Here’s my idea :
At the time as I write this, there is like 2 (maybe 3) weekly chestplates that have been introduced. The problem with those is that if you have diamond armor, you have to manually make the change to switch from diamond to custom.
My suggestion is to make this automatically, because if you have (i’ll take an example here) the fire reflection chestplate, you can put it, but if someone attacks you with a diamond, you switch to diamond, but if the player switches from diamond to fire sword, its very complex to put back the fire reflection chestplate.
I think it will be very nice, because like that their utilities will increase, and you can be more flexible like that.
I’ll respond to your commentaries in 1 or 2 weeks, so sorry to not answer sooner.
