What God of Moo said...Fel Leather isn't something you can wear 50/50, so gem PVE. If you get caught PVP'ing in them, your only option is to burst DPS like a madman as you will be gimped on survivabilty, so do as much damage as possible. Get Opportunist or some quested blue pants (such as the Leggings of Unending Assault from Nagrand) and slap the awesome 30 stamina leg armor on 'em for PVP until you can get your arena or honor gear.
