I understand the frustration with Ranald’s Gift, and here is why (in case someone doesn’t know how it’s calculated) — Vermintide 2 Wiki - Loot
Each Tome/Grim/Bonus gives you points toward a chest “tier”. You are given the following:
10 points per Successful Mission = 10 points
10 points per Quickplay Bonus = 10 points
10 points per tome … x3 tomes = 30 points
15 points per grimoire … x2 grimoires = 30 points
5 points per loot die … x2 loot die = 10 points
10-30 points for Ranald’s Gift = Sadness
However, for an Emperor’s chest you require 100-120 points. This means that upon a complete run collecting everything and acquiring all bonuses that you can…
x0 Loot Die = max 80 points = Ranald’s has a 33% chance to give you an Emperor’s Chest
x1 Loot Die = max 85 points = Ranald’s has a 50% chance to give you an Emperor’s Chest
x2 Loot Die = max 90 points = Ranald’s has a 66% chance to give you an Emperor’s Chest
I feel like we should be guaranteed an Emperor’s chest upon collecting “everything + 2 Loot Die”. I mean, it’s hard enough on some Legend missions to make it through the darn thing, let alone come out with a decent reward from an Emperor’s Chest sometimes. Maybe Loot Die can be worth 10 points each? This, of course, is my opinion and I don’t expect everyone to agree with it, but it sure does suck to put a lot of hard work into something to “Fully” complete it and come out with a silver medal, if you know what I mean.
Besides, the drop rates for reds are so low I almost thought I had Protanopia (don’t ask me what the drop rates are, I don’t know … but I’ve opened a lot of chests and only ever found one).
