Not sure if anyone's realized this yet, but the invasion armor that drops can roll warforged at any level, not just lvl 100.
Meaning you can potentially get your twink fitted out in gear rolling 10 iLvl higher than is normally available.
not huge or game breaking, but every bit helps
(just make sure you lock your EXP lol )
EDIT:At this time im getting mixed responses to items being increased iLvl or not for lower level gear. what appears to be going on is there is two levels of warforged for gear (at max this would be 710 and 720). if your lower level gear rolls what would be 710, it keeps the same ilvl. if it rolls the equivalent of 720, you get an ilvl upgrade.
EDIT: Todays patchnotes include the following:
"Fixed a bug that was preventing some lower-level event reward armor from gaining item level upgrades when Warforged."
At least it seems like I'm not the only one that experienced this, but I guess it's not going to be a widespread issue because most of the people save the boxes until 100 anyway
It seems Invasion gear can Warforge 2x. not more unfortunatly... i would love to have some Titanforged gear on my twink... i've been farming like crazy on my hunter twink and i've got all but 3 pieces ilvl 34 on my lvl 19 twink...NEED FULL SET O_O ... i play so much invasions i literally dream about them... Demons are haunting my dreams. btw Weapons can also warforge Twice! this is your chanse ! take it.
