Idea for big events!

[Thrasher]

Today when i was playing Defiance, i was thinking "What if there were really big world events?" Like maybe some sort of a HUGE boss (And im not talking about arkfall boss huge) that can wander around a big area.
I think it could be damn awesome it they did something like that, maybe they could add it for free in a DLC.
But that was just my thougt on what that could happen in a big event.

Please comment if you have an idea that would be really cool to see!

It would be cool to see a Helion wandering around randomly while everyone chasing it trying to kill it.

Also, we need high speed chases. Everyone drives around after a Raider Tank or some **** and tries to ram it.
