Returning Player - How to spend Gold &amp; Dust. Hi,

I'm coming back to HS, the last expansion I played was Kobolds &amp; Catacombs / a little bit of The Witchwood.

I have 3,000 gold and 10,000 dust and just wondered what would be a good way of getting back into the game? Buyings some of each type of pack or focusing on the maxing the latest set and continueing from there can slowly catch up with the rotation.

My gold characters are Druid and Priest would like to do something like that again. I prefer later game making bigger minions type play over 'smash face as fast as possible'.

Appreciate any guidance.
