It's extremely obvious BL4 was rushed out the door. In the 8 months since release they've been unable to figure out what exactly they want to do with the game, and the endgame remains absolutely fucked to the point they can't even get basic shit right.
For example, when I first beat the campaign there were 2 options: start over with a new lv1 character or create a new lv30 character with the campaign beat.
Where it gets retarded is if you chose the lv30 option you still start like you'd never beaten the game: no fast travel points unlocked, no SDU upgrades (making the bank unusable because it shares inventory across all characters so will be full by default), you were basically starting from scratch except halfway to max level and with shit gear (and the game defaults the difficulty to TVHM1 making it almost impossible to kill anything).
Where it gets double-plus retarded is the devs eventually fixed this in an update, except they just broke it in the opposite direction so now if you restart with a with a lv1 character they'll have access to the full map right off the bat. As far as I can tell the only way to start a legitimate new playthrough would be to delete your save.
And even beyond all this it doesn't really matter because there's nothing to do in the endgame except complete bounties --only half of which are worth doing because anything that involves you carrying an item means you won't be able to use your vehicle and have to walk all the way back to a deposit box-- and farm the same 3 Primordial Vaults to get better gear to farm the same 3 Primordial Vaults.
It's legitimately amateur hour shit, they're evolving backwards.
