There is a new-ish site which indicates which item on your character will benefit from Valor Points the most according to your class and spec stat weightings. Wowupgrade.com.
Cool stuff, and a great idea. Check it out.
That said, the best use of Valor for me is buying new gear, not upgrading. I suppose it should be obvious, but I jumped straight at the tool to see where the bang-for-buck was, and initially forgot to consider the purchase.
eg. 1500 VPs to upgrade a 476, or 2200 VPs to buy a 489? Get the 489 every time, as it can be upgraded later to even higher. Then once all the purchasable VP gear is obtained, then start the upgrade spends as per the site’s recommendations.
This week if I cap the 1000 pt limit successfully, then I’ll be darn close to the 3000 hard cap as well. A spend is a must do. This is a great problem to have, as I can replace either a set of 476 Bracers or Legs.
The choice then becomes between the two items – the bracers have Exp and Crit, where the Legs have Mastery and Haste. No brainer – Legs. I have no idea what the dps increase will be by upshifting 13 item levels, but it moves to what are almost perfect DK stats. And when they get replaced by 5.2 stuff the Mastery might be re-used in a Tank set.
I’m soon off to spend VPs – Wheeeeeee.
