I was on the ptr the other day testing out my trinkets on what not. As fury, I found that the empty drinking horn is actually pretty good for single target and way better for aoe fights. This is probably due to the ability for Rampage and Whirlwind especially to get 30 stacks extremely fast. The class trinket seems viable for single target as long as you can keep 10 stacks for the majority of the, even more so if you possess the talent endless rage. I have to test the trinket from Kormrok, fel lord and the Gorefiend one.
