A lot of other items already stack. I never understood why mods were never changed to stack. It would help lower inventory and bank bloat tremendously. I have 8 characters just for holding mods.
I know I can make a Reforged character, and do the new dungeon, but I'm someone that likes playing my original characters in games. I just hope it isn't going to be the norm for all new content to be locked to Reforged characters.
I've played this game off and on for 20 years, and it sucks that you have a limited time to get special weapons for builds. It limits the ability to make a new class, then enjoy everything available. The Proofs should be a permanent system always available.
It would also reward newer players with a bank slot, and being able to play some of the really fun builds with the weapons. I just never really understood why something like this is limited to yearly.
I know people will say how this idea is bad for some inane reason, but any event that is required to have new builds makes no sense with a game about pushing the limits of creativity. I also have said weapons, so I'm suggesting this for newer players.
