I thought the event started at 6pm as per this info:
But clearly I must have screwed up the time zones.
I am at work right now, but if some team needs me I will leave early and head on down there.
If it is indeed season 5 format, warriors will be useless anyways.
Its only S5 gear and although S5 gear doesn't really favour Warriors that well, Blizzcon and EU Blizzard Regionals were both won by Warrior comps (TSG and WLD), although it'll be impossible to have that level of teamwork with a random people, still shows that its possible to do okay in it.
