It's sometimes difficult to play the same class in two seperate ways. The other day one of my guildies on Ally side was about to run through an instancee for some shards when I logged on. He asked me to come along to keep him company and told me to bring my level 30 mage so I'd get some exp out of it. Anyway, he pulled a whole group of mobs with his kitty and at this point he would throw a volley usually. So I ran in, frost nova'd and jumped back to throw down some AoE action... barely phased them, Apparently fros AOEs aren't as effective when you're fire specced o.O
On a different occasion I was on my undead mage and this same guildy was on his lock (yeah, it's the same guild with the same people on both factions lol). Anyway, we were grinding out some quests and we're about to start a pull when I hit my 8 key. Well, with my undead mage being frost specced, my 8 key on him obviously isn't pyroblast, lol. So he says "GO!" and I sit down to eat, haha.
