Not really sure what your post has to do with the post you quoted. All I see is a suggestion that tangible rewards be offered for ballista as an attraction to those who might not otherwise participate. There are those of us who would like to see Ballista develop a bit more and not be seen as just a little minigame to smack your best friend around in.

As you pointed out, PvE and PvP in WoW each offer gear that is most desireable to the relevant crowd, and the best PvP gear is not the best PvE gear or vice versa. It's perfectly possible to have nice rewards for participation without them being out of balance with everything else.
