So the devs have said that currently the renown system is not working as intended, and I can accept that. We all want to get renown as quickly as possible for the competition, and we will when the this update hits live because all guilds will want to try out all the new shinys!
I decided to start keeping track of the numbers while helping my guild farm renown in Epic Von 1 (yes, the secret is out, sorry to those who thought it was so brilliant) and here are my humble results:
After 70 runs (of killing the first 7 mobs), killing 490 monsters, I saw a bag drop rate per monster of 10.61% We could say I was probably a little on the lucky side, and it's most likely a 1/10 drop rate for monsters to drop a loot bag.
Of the 52 loot bags I saw, 6 had renown in it, for a drop rate of 11.54% per bag or 1.22% per monster. The renown per bag ratio is either 1/8 or 1/7, would need more testing for an exact figure, but my best guess it's one or the other.
Once pulled a renown, the amount you get in epic Von1 almost exactly followed: 45% gave 50, 45% gave 150, 5% gave 500, and 5% gave 1000.
The bag drop rates might be different from different mobs, but I have seen devs mention it's supposed to be the same.
So, it is the intention of the devs for players to NOT farm loot bags for renown, I have seen this said multiple times. It is, however, the intention of the players to get as much renown as we can as fast as possible. So I would like to offer a few humble suggestions to the devs on ways to make running full quests more appealing other than just going around nerfing loot bag drop rates:
-Increase the renown drop rate in end rewards significantly. Right now it's incredibly rare, almost unseen. I would suggest it should be as high as 50% chance, maybe 1/3 chance.
-Increase lower limit of renown drops from chests and end rewards in high level quests. IE: a lvl 19 quests should not drop 50 renown from an end reward.
-Include large sums of renown in raid loot tables. Make it a rare find in warded chests where you could get hugs sums of renown, also something that pops up on the 20th run like other raid loot items (oh the horror of choosing between a +3 con tome, or 10,000 guild renown!)
Be also nice if a Dev could tell me if my numbers were accurate
