Can I use your time traveling device after you are done? There are some... things... I want to do involving certain fellow high school classmates.
On a side note the likelihood of Blizzard making yet another faction is extremely slim to non existent. They are already getting a ton of flack of faction X is better than Y, add Z into that and it will just get crazy. Not to mention how would you balance something like that with achievements into the game? Way too much hassle to be honest. Would rather they spend their time making ball tightening raids.
