Ok, after having finished the lumina quest on release day.... Its not that difficult, at all. This was by far the easiest quest we've had, i suck at pvp and managed the handgun kills portion in about 6 games. Friendly HC kills count toward progression as well and theres no death penalty. As for the gambit part i mean, truth. Its that easy. It doesnt even have to be a spawn kill or a kill within a certain time frame, you just gotta kill the invader before they kill a teammate which is turthfully very easy to accomplish. On the orbs part just farm EPs with a masterwork weapon. Since EPs are part of the quest everyones farming them so it took me about 3 levels to get around 30ish orbs. Everyone made this out to be impossible but this quest is so easy you can finish it in less than 8hrs without much effort at all. But i still agree, putting pvp steps in a pve oriented gun is kinda stupid and pointless, then if you know the lore behind rose/lumina it makes it even worse. But still, id do this quest 100 times before i went through TLW, thorn, malfeseance ect ect even 1 more time
