I don't mind them being left behind. They're just being left SO far behind that new uncommon will be stronger... that's what I have a problem with
That's how these games work though: even the strongest shit in a certain time period of the game, will become some of the weakest as the game life goes on. As for the exotics: i dont think they will be that bad until we start reaching level 37+ enemies. I say that cause the attack power for our shit now is 365, and when ttk drops, they will be whatever the equivalent to that is. So that means the weapons should still be good for at least another level or 2 (up to 36). After that, you can probably still use them, but they will be less effective. Which is how it should be.
