Hello again.
The following talents provide no double-dipping effect:
- Improved Tracking
- Rapid Killing
- Improved Steady Shot
- Marked for Death
Which leaves you with RWS (always present), Focused Fire (almost always present(, Ferocious Inspiration (this is a BM talent but Rets bring an equivalent buff - but bear in mind you're not always within 40 yards of a Ret), Culling the Herd (abysmal uptime in PVP that's borderline 0%, especially when your pet dies within 3 seconds of making it within melee range of an enemy target), and of course the 2P proc, which is rather notoriously powerful when it does proc, which in PVP is barely. My usage of the phrase "more than 10% or so double-dipping in most situations" evidently stands valid.
