Premade character copies where allowed, and when the PTR first went up, we came to find out that warlock premades had been given a npc mob's SoC spell.
This one casted like you would an AoE Blizzard/Rain of Fire at no mana cost, instant cast, 60000 yard range.
They fixed the bug within hours of launching the PTR, however I managed to get in some video footage before the PTR shut down. You were even able to cast it while you were dead, mounted, etc.
I filmed and edited this in literally like 30-45 minutes, so I look forward to many people making comments about poor editing and whatnot.
IMO This is what happens when warlocks get mad :P
I also tried to upload this in DivX format to Stage6, but it kept saying it couldn't find a connection when I tried to upload, so, sorry for no Stage6..
