So, I'm sure other 10 man guilds have felt the same way, but now there is proof.
Look at the huge discrepancy between 10m and 25m loot. Average ilvl from 25m is much higher than average ilvl from 10m. It's a fact.
This should be looked into, and I feel that I have a pretty simple solution.
6 pieces of loot drop off a 25m boss. 2 drop off of a 10m. That is a 3:1 ratio, when the raid size is a 2.5:1
This is easily fixed by any bosses that drop tier, still drop two other pieces of loot, and tier. Therefore, making 3 pieces of loot drop off of bosses that have tier in 10m.
If you compare them, you can see it in this link
You may have to go to the individuals guilds to see comparisons between 10m and 25m, but still, the difference is clear, and there should be a solution to fix this.
