Dungeon token increase
You are probably both right. I remember back when I was still doing exp prices were sometimes off. Some dungeons had different prices for different items (chest/shoulders iirc) This may or may not have been fixed recently and upped to the correct amount (doubt it). That is probably what you are seeing.
Of course it has been awhile since I went and checked prices or did explores so /shrug.
The prices didnt change it all. I got my dungeon gear shortly after release of the game and it still costs exactly the same now, the only difference is, its easier to get the required tokens now.
To my knowledge the only exotic dungeon set that is cheaper than all the rest is AC, can’t speak for all of the dungeons but CoF prices haven’t changed, they have always been the price they are now.
It’s always been 330. I got my HotW dungeon set like the first month of the game and it was 330.

Lower level dungeons pieces used to cost less token because they weren’t 80’s exotic equipment.
