Definitely not. With your gear all the hit will go to waste anyway. Unless if you can get 2 weeks worth of valor before the patch drops then you shouldn't even touch it. The 510 bottle is miles ahead of the VP trinket with your gear because of the hit.
Buying the VP trinket would be worth 7 item upgrades (250 vp for 1 upgrade 500 for upgrading the entire piece). It would be much more beneficial to spend the 1750 on your other trinket and bow with the vp from that. After that I'd upgrade your H tier since you will never be replacing those. Then save your VP since you could get something to drop.
