Totem FB vs GC

Hi,

Keep in mind I play HC and this questions is only for HC.

I'm having alot of fun playing totem build with FrostBolt.
However this build is a good starting build for farming safely in HC, until red maps. I suppose you could still farm t14-16 but its not recommened becuz itll keep getting worse....

In Totem GC I have no experience, but the videos look awesome...and i read its better against bosses...

Now my question....

Which build is better, and for what?
Will GC be able to clear high end game content in HC? Or will it still be the same thing just a little better but no real chance in doing any high end bosses?

Reason I'm asking cuz ima start HC flashback with either 1 of the 2, not sure which :P

Had a GC totem bro join me to help clear my atlas of the elder. It was embarrassing. I'm running around trying to stay alive and do a little damage. He just stood there while his bazillion totems sprayed ice.

Looks good to me. Never played totems before but I think GC can hit multiple times? Anyway.

Nice name.
