Some way to turn the "bad" aka the basic, rare and epic lamps into mythical would be a great change. However, I personally dont like the idea of going above that.
Something heavily related to this topic are event lamps/backpacks. I was not a high level player back during the christmas event and yet, my inventory is full of nearly 400 christmas lamps and backpacks. If the current early concept trade in they talked about in the news tab is implemented without any changes then I guess I just trade them all and now I have every ??? lamp/backpack in the game and nothing is worth anything anymore. This is a problem that will only get worse as im sure other events will also give you free stuff. I would probably have 400x that if I did the christmas event now.
-# Alternately, the devs could remove all the basic, everything in rare (except the tech visor) and all the epic lamps from the game since no one likes them anyway and their only existents at that point would be to be sacrificed for better lamps. Its not like anyone would lose anything if they suddenly disappeared from everyones inventory over night.
-# I think if they got rid of the "fluff" and just handed out regular head lamps to each player and all that was left were the mythical and limited rarities available to craft then practically nothing would change.
-# The lamp shop is a weird topic. 90% of the hats are not mythical and thus not worth crafting. It could just sell 1 or 2 endlessly cycling mythical items every day and not much would change from our current system. People dont like it now and even after this change, people still wont.
-# Hell, even getting rid of that one terrible "buy 3 lamps" quest would be a good thing.
