They could start by separating the sandboxes entirely, such as completely splitting pvp and pve progression meaning you cannot use pvp weapons and armor in pve and vice versa, they need seperate progression paths but that also means they would have to add stuff to pvp that would be valuable to pvp players. Also supers would have to be balanced completely separate and I am fine with that, maybe some of the poopy supers would then get buffs in pve and pvp to be more usable in the sandbox. Hate me if you want but this would solve a ton of problems such as people joining pvp activities only to complete bounties and be a detriment to your team (seen this before) and it would also keep pve players from playing it if they are not good enough or just do not care. Could also be a boon for pve players that want to use autos or fusions (they are a joke rn) seeing as how they can adjust the numbers without having to marry it to both sandboxes, it would also fix balance for pvp and pve because they are now isolated from one another except exotics. The upside is they would be tuned separately in the sandboxes but it would so give both sides of the coin to start with a base floor without the "oh this would be an extremely awesome cool new gun we could make" says carl, but jerry puts the brakes on and says " no carl, it would completely break crucible" that type of situation could be remedied because both sandboxes are separate so tuning would be much easier and it could solve the problems of crucible "balance" I guess, though a lite mmo with looter shooter mechanics and competitive pvp is hard to pull off, but we could see some changes that would make the game healthier for everyone methinks.
