Bungo messed up when they added the new tiering system exotics were supposed to have an upgrade path that would raise them from what was tier 2 drop level with poor stats to tier 5 with high stats only it wasn't ready. Stupidly bungo added them anyway stuck at tier 2 stats with a promise to add the upgrade system later only so far it hasn't appeared or even been mentioned in ages

For some reason, exotic armor being higher than T1 or 2 would be OP. Yet it baffled me that they keep releasing so many weapons that are even worse in that regard than armor. I'm pretty sure I've read on here from other players when I brought this up before that Bungie said they're going to let us get higher tiered exotic armor. Idk if that's true, but I hope that same treatment extends to weapons as well. If they aren't going to buff the stats of every exotic weapon to keep up with stat monsters (in some cases complete killing machines) like Martlet, Redrix, Immortal, Giver's Blessing, Mos Athanor, High Tyrant, or several of the weapons they're going to update in June like Eyasluna, then the least they should do is let us upgrade our exotic weapons to T5.

Exotic armour is no longer exotic it would seem. Call me crazy, but "exotic" implies "better than ANY of the regular armour"; yes, including T5.
