because it's not a ward... and the only way it's going 2 pwwn an entire team is if they are standing in the same room... most people on crackhouse will get sucked against a wall... it's only those in the exact same room that would be in serious danger.
void will also kill people through walls, so anyone in a room adjascent to the one in which the void goes off is also in danger if the void is close enough to a wall. not arguing that it equates to a ward, just a comment
Through the darkness of futures past,
The magician longs to see
One chants out between two worlds:
Fire, walk with me.
