I leveled mt 39 Pally to where he needed 8 XP to level to 40. I had already Obtained all my plate gear, and had it enchanted with Libram of constitution, Nethercleft Leg Armor, and BC Enchants (Stamina mostly). All blues (Where Possible) and 2 Epics (Boots and Wrist). Then I queued up for my Last 30-39 game, turned in a quest, went and trained my new level 40 spells, Plate Armor Profiency, and Mount. Then I entered the battle and fought my last 30-39 WSG as a level 40 alongside 2 of my friends on Level 40 Warlocks. We all were running Fraps, and they compiled a video of it. So, Enjoy =).
