Hello, WoW community! With all the hubbub around raid drop rates changing and the new Valor points coming, I thought I’d do a fun math exercise to answer a few questions about the current state of loot in Shadowlands.
Note that I’m not pitching any opinions here; I’m just presenting how the match behind the game’s design actually affects player experiences and outcomes. I’ll leave it up to you all to form your own opinions about what this means, because… well, you were going to do that anyways.
===================================
Castle Nathria Drop Rates
Up to now, Castle Nathria has been dropping 3 pieces of loot for a 20 person raid. That means on any given boss, you have a 15% chance of getting something.But with 10 bosses, there are lots of possible outcomes. So what’s the actual chance of getting different quantities of loot from Castle Nathria?
When there are 10 bosses, and 3 drops per 20 people per boss, here are the probabilities:
- 19.69% chance of getting no loot.
- 34.74% chance of getting one piece of loot.
- 27.59% chance of getting two pieces.
- 12.98% chance of three pieces.
- 4.01% chance of four pieces.
- 0.85% chance of five pieces.
- 0.12% chance of six pieces.
- 0.01% (1 in 10,000) chance of seven pieces.
With the above drop rates, your average number of pieces of loot earned from clearing an entire Nathria raid is 1.5 items. Of course, this is an average, so your own personal experience won’t necessarily reflect it. It’s entirely possible to fully clear the raid multiple times and get no loot, becuse randomness is random.
With the upcoming change to 4 pieces per 20 people per boss, what happens to the probabilities? This!
- 10.74% chance of getting no loot.
- 26.84% chance of getting one piece of loot.
- 30.20% chance of getting two pieces.
- 20.13% chance of three pieces.
- 8.81% chance of four pieces.
- 2.64% chance of five pieces.
- 0.55% chance of six pieces.
- 0.08% chance of seven pieces.
- 0.01% (1 in 10,000) chance of eight pieces.
This bumps up the expected number of pieces of loot per person per raid from 1.5 to 2, and strongly reduces your chance of getting nothing at all (from about 20% to about 10%).
===================================
Mythic+ Dungeon Drop Rates
The prevailing opinion in the WoW community about Mythic+ loot is that it’s too scarce, which makes Mythic+ dungeons less rewarding than they used to be. Valor points are coming in patch 9.0.5 to help players address that problem, but so far, you will still need to find the piece of loot you want before you can upgrade it.
This means that even with valor points, the scarcity of loot will continue to be a hurdle that players must jump over before they can get their upgrades.
So… just how scarce is loot in Mythic+? What is the probability of running a given number of Mythic+ dungeons in a row and getting nothing at all? First, let’s look at the probability of getting no loot for multiple dungeons in a row if you aren’t timing keys – so you’re seeing 1 loot item drop per dungeon.
- Run 1: 80% chance of getting nothing.
- Run 2: 64% chance of still getting nothing.
- Run 3: 51.2% chance of still getting nothing.
- Run 4: 40.96% chance of still getting nothing.
- Run 5: 32.77% chance of still getting nothing.
- Run 6: 26.21% chance of still getting nothing.
- Run 7: 20.97% chance of still getting nothing.
- Run 8: 16.78% chance of still getting nothing.
- Run 9: 13.42% chance of still getting nothing.
- Run 10: 10.74% chance of still getting nothing.
- Run 11: 8.59% chance of still getting nothing.
- Run 12: 6.87% chance of still getting nothing.
At 1 drop per dungeon, if you run 3 dungeons in a row, your most statistically probable scenario is that you get nothing. You need to run four dungeons before you’ve tilted the probabilities in your favor. And by the time you clear your 7th dungeon, you have a 20% chance that you haven’t seen any loot still.
But what if you start timing keys and get 2 drops per dungeon?
- Run 1: 60% chance of getting nothing.
- Run 2: 36% chance of still getting nothing.
- Run 3: 21.60% chance of still getting nothing.
- Run 4: 12.96% chance of still getting nothing.
- Run 5: 7.78% chance of still getting nothing.
- Run 6: 4.67% chance of still getting nothing.
- Run 7: 2.80% chance of still getting nothing.
This is a dramatically different result. At one drop per dungeon, you had to run four dungeons in a row before you would probably get something. At two drops per dungeon, you will probably get something by your second run. And the numbers compound pretty dramatically as you chain more runs together – for example, you are 10x more likely to have no loot by your seventh run at 1 drop per dungeon as you are at 2 drops per dungeon.
What does all this mean? I don’t know! But I thought it’d be cool to inject some hard numbers into the conversation about the current state of loot in Shadowlands. So I hope this was helpful!
