I don't have access to any raiding gear but I've been using the Amani Longbow / Angelista's Revenge / Shard of Contempt to moderate success. I'll swap back in the gladiator thrown if I'm feeling squishy (I can do that after the arena starts too).
My instinct tells me that the Shard is better than the Berserker's Call that I've been using previously, but I still haven't made up my mind yet. Having 5.5% more hits connect against many classes is definitely noticeable. (And yes I try to attack from behind as much as possible but it's not always doable)
I also have a Red Belt of Battle lying around but I guess it's not worth using if hit capped already.
I'm not really recommending anything, just some random thoughts if anyone wants to give more feedback.
On another topic: I'm really liking Endless Rage but I've been thinking a lot on how to best spend the filler points and I can't make up my mind. I have 45/11/5 at the moment with 5/5 Improved MS and 2 points in Improved Bloodrage, but I could also spend those points in Commanding Presence and Enrage. Here's a list of the possible variants:
45/11/5
41/17/3
45/13/3
I know I'm nitpicking here but any opinions on this?
Edit - Replying to the post below: I've read that page, there's even a post of mine on it, it's just that every time I respec (which is like 4 times a week) I keep asking myself that same question and I haven't been able to decide yet. I was hoping that with more people playing ER and more time passed since 2.4 some folks had formed stronger opinions on the subject.
