So we got rid of bonus rolls on bosses but…
What if we had an option to “re-roll” the great vault.
Of course it would probably come with a price, gold, anima, or something.
And I doubt they would add a “bad luck protection” to prevent it from rolling the same pieces you had first time. But would be nice if they did.
I think of anything more than a single option as the rerolls. Not that any of those additional options were good for me this week 
I’m just excited that I unlocked a second lfr slot and both items available were stuff I had on. 
I could be for reducing the chances the rolling duplicates of the same or lesser ilvl (but not removing them, because then the loot table shrinks and people can just target things). You just get slapped if you’re looking for a nice piece of 226 gear, but you roll the same shoulders/trinket/etc. in one slot, which then leaves only 2 more to roll something you can actually pick, for example.
Maybe an option to re-roll one piece out of however many you get. I’d be cool with that.
The Great Vault should have a re-roll functionality getting the same items every week just seems like a waste of time it kills everyone’s motivation to play the game or at least mine this game has potential to fun but keeps hitting that barrier the community is dwindling leak of ability to catch up…being left behind really sucks I want to do higher content with my fellow Guild and Friends but since i work full time I will never have that chance to thrive as a wow player.
The developers don’t care if you get left behind on tier gear.
They care about MAU and token sales. The more unfortunate your RNG is, it is actually better for them.
They don’t design this game to be fun anymore or have great content. They design it to suck as much money as possible from us with the least amount of development work required.
