Personal opinion, it's up to you to score if you don't agree with what I say.
VIP: Ok, personally, I never liked those VIP gamepasses that give you a VIP title, cosmetic, chat tag and XP buffs. The one in DQ suffers esactly from this problem and it just becomes a cliche to this point. I don't care about the cosmetics. The 20% XP boost is subtle but it's not really a game changer (I don't own it). Unless you don't play every day because you have school or you're looking to climb the leaderboard of the no-lifers, don't buy. 4/10
2x Gold: A good gamepass considering how grindy DQ can get, but we never feel that we get enough gold even if we own it. Either vCaffy buffs gold for dungeons or sell value of loot. Still very useful to=hough. 7.5/10
Extra item: Gives you an extra item every raid, which give you extra chance of getting the item you want, get more gold or transform non-hardcore to hardcore assuming there is no extra item drop activated. The only problem is that it costs 2000 bobux. 8/10
Free resets: Why does this even exists. Why. This is just a money grab for newbies but even if you are suffering from Tourettes (no insult, I'm just comparing) no one really messes up placing their stats to make you character decent for the dungeon. And it's even worse when you see that the amount of gold you get from your current dungeon is like 100x times more than what you need for resetting. 1/10
Boosts: They're decent, but I wouldn't use them if you're struggling, DQ is meant to be enjoyed (sometimes) and boosts feel like cheating. But if you got banned on your level 200 account with every legendary and every cosmetic, and want to catch up to date, feel free to use them. 5.5/10
