I just want Bonusrolls back asap.
GV is a horrible design. I get nearly no raidloot, m+ loot from dungeon chest is to low and the upgrade system capped at 246 (yay...). So when i log in an go raiding, i know "hey there is a real low chance to get loot" - unfun. when i play m+ i know "hey you wont use any of that loot". I just play to fill my GV frustration with 2-5 options and have to hope that i wont get garbage to pick at least 1 upgrade.
As mentioned before its a horrible design.
If Blizzard dont want to bring back Bonusrolls for Raidencounters, bonusrolls to exchange 1 offer from the great vault to another random offer would help a little. But right now the complete system is unfun (to me). btw i never wanted "meaningful loot" i was quite happy with wf/tf and corruption with vendor was fun!
