No to the commendation bonus buff, that trespasses into p2win territory. The no rewards past X warzones idea, similar to the flashpoints one, maybe. On the one hand that means more f2pers in blues to beat. On the other hand that means its more likely I'll have f2pers on my pvp teams, but then again, I don't play sub-50 pvp, so the input from someone who does could be more valuable.
How does that tresspass into P2Win territory? If gear is THAT important, then the system is already broken. I'd welcome any possibility to accelerating PvP gear collection so that everyone can PvP on equal footing as opposed to grind2win.
