Sorry for the confusion.
We were worried Arms warriors were doing too much damage, sometimes, when the RNG was in their favor. We attempted to fix that by lowering the proc rate of Sudden Death, but of course the RNG aspect just went up when we did that. We still might try alternative implementations, a 50 rage max Exectute perhaps, but we will probably not mess with it until we see Arms at 80 on Live in PvP and PvE to get a better idea of how the build is doing. (Note the adverb "probably" -- if we do end up changing it sooner, please don't tell me I broke promises to warriors.)
I sometimes try and mention potential future nerfs or ideas for nerfs that we rejected, so that A) I'm not always bringing bad news about nerfs, B) If we do end up nerfing something in the future it may not be a total surprise, and C) You get a little more insight into how we work.
