I wanna know about pve. Can you cast mirror image and your water elemental at the same time. If you can then you have 25 dps out there at a time. Even with 20 things doing dps you might be able to burn down some bosses. I watched a video of 5 mages doing heroic magisters terrace. Which was the hardest heroic back at level 70. They were able to do it alot like 5 shaman were able to do it also. They would spread out and bounce agro from the boss poping ice block when the boss was about to kill them. What kind dps can you kick out with mirror image might be able to take some bosses if you can make it ~15 seconds.
