I think Exotic armor should have the ability to equip any mod otherwise I don't mind it at all. All this does is require you to have multiple sets of armor instead of using just one piece forever. For example I used the same chest piece from Forsaken launch to Shadowkeep launch (so a whole year) because it rolled with both Unflinching Rifle and Small Arms. I used two legs because one rolled with both Rifle and Small Arms Dexterity and I had one leg with Traction. So now I have to have 3 pieces of each now, I can't rely on one piece of gear for a whole year. I'm ok with that. But again part of what makes Exotic armor exotic is it should have the ability to equip any mod. Because I agree having Exotics tied to an element limits it's build capacity.
