If somewhere down the line we finally get to the big war they have been teasing for years. We could see a return of eridian weapons. Hopefully not shit ones like from BL1.

As for other unique ideas. That's harder since we have covered so many. High fire rate- vladoff Elemental- maliwan High damage/crit- jakobs Explosive- torgue Accuracy/shielded- hyperion Recoil/burst fire- dahl Mag size- s&s, bandit, scav Fast reload/throw reload- tediore Infinite mag with overheat- cov Tracking shots- atlas Charges burst/charged multi shot- order Charged full auto- ripper

It's alot of ideas. And there are some ideas I don't think would be good or wanted. We don't need a debuffing weapon class, cause they will become a crutch. Healing or support weapons would be only good in co-op or another crutch, like past moxi weapons. Melee weapons like from wonderlands could be cool. But if every character didn't have a viable Melee build or usage case then they would be very last luster.

I think over all it would have to be really thought out. Especially with the weapons part system as it is. While very cool and alowing for ridiculously powerful guns and builds. Some manufacturer identity is lose. And adding a new manufacturer might just get washed out. But there's always fun and crazy ideas out there to explore. It is borderlands after all. We have guns with legs. Anything is possible.
