You already RTB prior to the pull and if you get a decent set of buffs, you're not going to reroll it just because you get a free two-fer. This ability needs to be a bit stronger or more flexible. It should allow for ALL rolls during AR to be two-buffs, or guarantee a single three-buff (I'd personally prefer a free 3-buff as this would feel extremely significant and beneficial).
As it is now, it's going to be extremely marginal in everyday play and will frequently just not get used. If you're mid-fight and AR comes up, you just aren't rolling away from what you have because of the proc. Good concept for consistency but this isn't as juicy as it sounds if you really think about how rarely you'd end up benefiting from it. It basically just adds a soft floor for the DPS, not any kind of top-end gain.
