So it seems to me (a new player) that if you stack all these Hoth characters your deck would be incredible. Yet I never see all goth at the big tables on YouTube. Thoughts?

Hoth was the first cycle released, and wasn't really a viable archetype during most of the game's life. It got a little bit of support during the Echoes of the Force cycle (one Rebel, one Imperial), we didn't see anymore Hoth sets after that until the second to last pack, when the Rebels and Imperials each got one new Hoth set that finally made them playable again.

I think its still undecided if they are playable but, the new sets were definitely an improvement.

 

The main issue back in the Hoth cycle was that they attempted to merge vehicles and characters into the same sets which caused your deck to pull into two directions. A great case being wedges set which was a for a speeder deck but then had an enhancement more suited to characters.

 

So the speeders and walkers ended up being the decks that came out, while the character/trooper decks took a back seat as there wasn't anything to get them to work with, any decks that did come out were not up to dealing with the new cards.

 

Ideally what we need is a return to Hoth set/cycle. Something that looks to fix or replace out parts of the Hoth cycle so that you can have a stronger and more synergised decks, that are still on theme. If I come out of retirement maybe I'll design something.
