Anyone else noticed that when queueing for Raid Finder it calculates your off-hand as zero (thus lowering your Raid Finder ilvl) when you are using a 2-hand weapon ? I just got my Retri Pala to 470 but Raid Finder says 461.
And what i know is PvP gear doesn't get scaled down ilvl-wise when queueing for PvE content.
You had 461ilvl before equiping new weapon, right? Just relog and try again.
I supose that ilvl update function for dungeon/raid finder is only called once at logging event, so you have to relog to refresh your ilvl for it.
