This suggestion has probably been made, but here goes.
When you fight your way through hordes of Cave Trolls and finally make it to the Champion lvl Troll guarding the chest o’ loot at the back of the cave and it takes a party to kill him… I think that there should be some decent loot (green or above) or very useful (crafting) in said chest o’ loot, however much to the sorrow of our party every one got crappy blues which most of use could not use in the first place.
I will say that we had a lot of fun exploring the cave and fighting a Champ at the end we just wish there was decent loot at the end, it would make it so much more exciting.
