This is where we differ.
I acknowledge that what I am doing is not the meta and, while it works fine tanking at the +15 level, I cannot speak to higher keys. I imagine that the better defensive benefits of reprisal become necessary as you approach +20. But then, most people are not doing keys that high. I haven’t tried reprisal since I don’t do Torghast anymore and don’t have any soul ash. Also, I would hate to give up the revenge spam.
But my point is that, contrary to the original post, I find revenge to be very satisfying. I suppose the animation could be made better, but it’s still nice to see all the yellow numbers pop up. Also, while no individual cast is a “big spend”, I do think of it as a big spender since I am dumping pretty much all my rage into revenge for about 10 - 12 seconds. Obviously I need to be swimming in rage to do that, and I need to use a defensive CD. The idea is to combine ancient aftershock + avatar + ravager + last stand w/bolster, then spend big on revenge. Sometimes I will leave out last stand since its CD is longer than the others. In that case, I would just spend some rage on shield block or ignore pain.
This is not an ideal case but my last key was a +12 Necrotic Wake. It’s a bit low, and the mobs tend to leap out of the frontal cone a lot – which is similar to one of the issues people are describing in this thread - but here are some screen shots of what I am talking about. Note that all of these are individual packs, I am not “pulling big”.
First pull, G1, 4 mobs
Fourth pull, G5, 5 mobs
First major pull after Blightbone, G12, 5 mobs
Meter for the Blightbone trash (revenge is 44% of overall damage)
A cheeky prideful pull, G22, 8 mobs
Before Stitchflesh, G30, 4 mobs. The group really blew up this pack and I ended up 3rd on the meter.
The other corner, G31, 5 mobs.
In only one of those pulls did I have the prideful buff. I am sure that people can put up better numbers than this, but my point is that I find revenge to be a very satisfying ability. Actually I was kind of disappointed in this run – it was a pug and we had some awkward pulls. Also, I do consider revenge to be a big spender in the sense that, during the cooldown window, I am dumping almost all my rage into that one ability. I certainly would not consider revenge to be a filler ability. A rage dump, yes, but outside of these cooldown windows I have to be careful about spending rage on anything other than shield block and ignore pain.
One last point: I certainly hope Blizzard agrees that revenge is not satisfying – buff it more!
