My best event is this Goblin event.
Cuz i have get the Poison Assault gear set for mage, makes me stronger .
And Nilbog, 60k with opening Hoarded chests and finally the Goblin vanity .
1 word for this event....... its... NICE

But a few things I think about whats wrong with this event:

a platinum tier missing, just only get points for a pet is not so good.
cuz nilbog is not as good as soms legendary pets
And maybe make a banner for everybody who started the event.
