Any tips on goblin killing for me or should i just ignore them from now on?
Actually, they are easy once you know the technique. But you have to unlearn what you've learned, young padawan. :p
The key is NOT to permafreeze them until they stop moving (right before they open the teleport). Else you waste your Frost Nova and increase a gobbo's crowd control resistance. And that's because the dash gobbo's have is a CC breaker and it'll break any Frost Nova you initially cast. But if you wait until they stop (typically after the second dash), then you can lock the suckers down pretty easily. It's very straightforward to lock them down on any MP-level once you get the hang of it. The other option is to keep a crowd of monsters handy, but that's really unnecessary.
