I’ve been asked to post a suggestion regarding Eridium, and found this post, so I’ll add mine here to keep the topics merged.
Eridium is currently a wasted game resource that can be put to better use elsewhere. Once you hit the current “end-game” at level 50 and start farming for legendary Anointed gear, Earl’s “Veteran’s” vending machine becomes rather pointless. You’ll find that even after you’ve purchased all the cosmetic stuff from Earl, you’ll accrue Eridium faster than you can spend it. Right now I’m sitting on over 9k Eridium with nothing to spend it on, and I’m far from alone.
The premise of my suggestion is similar to the OP, with a few noted differences.
Add a feature to the game that allows us to modify an item/weapon modifier at the cost of Eridium. There’s similar systems in other games, such as rerolling a perk on a weapon with Phoenix Coins in the Division. Here’s what I propose:
Allow players to select one modifier on a gun, class mod, or artifact and for a flat rate of 100 Eridium, they can reroll that modifier to select a different modifier. The rerolled modifier would be random, but it will not be the same as the prior modifier. You can reroll as often as you have Eridium to spend.
Once the first modifier has been rerolled, then allow players to select a second modifier to reroll at the cost of 500 Eridium, same conditions apply. The rerolled modifier would be random, and not the same as the modifier you’re rerolling from, but you can reroll as often as you have Eridium.
Once the second modifier has been rerolled, allow players to select a third modifier to reroll at the cost of 1000 Eridium, same conditions apply.
I would also recommend that anything which has been rerolled cannot be traded to another player, and if it’s dropped, it can’t be picked up by another player (similar to the Golden Chest when it’s first opened by another player, only there would be no release timer). This would prevent players from creating a perfect item, then duping it across the player base which would completely undermine the entire game mechanic.
(I excluded grenades and shields intentionally because they don’t have modifiers like other gear does, and changing an attribute of a grenade or shield could fundamentally change it’s nature.)
To summarize, this feature would effectively allow players to reroll hard-farmed gear in order to optimize it, while simultaneously encouraging Eridium farming. Given that the reroll is RNG, you could easily spend 9k Eridium rerolling a single item. I feel such a game mechanic would be win-win for both the longevity of the game and the enjoyment of the player. It would help make the nerfed loot drop rates not seem so harsh (I’ve lost count how many times I’ve seen zero legendary drops from a boss in Mayhem 3 TVHM), and would alleviate some of the tedium from farming gear and bring more players out of pre-patch mode. It would also promote Eridium farming by players, since the resource would actually have value beyond the limited scope of cosmetics, or the “Veteran’s” vending machine which most players stop using once they start farming legendary Anointed gear in the “end-game”.
If this feature sounds good to you, then please express your support for it here. As they say, the squeaky wheel gets the oil. If there’s enough support, perhaps Gearbox will consider it.
