So, i've been using this trick myself during the latest patches which included itemupgrade systems.
How-To:
- Cap 3k Valor Points the regular way(3 weeks)
- Wait for Weekly Reset, Purchase a Random Valor Item and start a timer counting down 2 Hours.
- Begin Capping your Weekly Valor Cap.
- Before the timer runs out, shuffle items from the vendor and refresh any timer you had on the items.
- Once capped fully again, you should be able to have valor points "Stored" as items in your bags.
The timers on these items ONLY tick when you are logged into the game.
I did this myself from 5.1->5.2 having about 11k Valor Points which enabled me to Upgrade all of my gear the first day, and any gearpiece i've ever recieved up to this point.
Now there should be enough time for everyone who're already capped at 3k, to get 5-6k Valor Points before 5.4 comes out.(Yeah Itemupgrades wont be removed)
