Statsically speaking, based on the results from last event, its Priest, Druid first followed by Mage, Warlock, Rogue hero power.
I dont think these are relevant in any way ... there were different cards in the mix and there was a different drafting system. Makes a lot of difference.
True. Have to factor in the cards from WW and BDP, which have a small amount of arena meta changing cards.
The rankings of hero powers should be still relevant though.
I'd put Warrior as one of the better first classes due to Warpath and Super Collider.
I drafted (only) two warrior decks and i was offered very few weapons and all of them were only FWAs and Reapers. But i have played vs a lot of warriors and they also had like one max two weapons from what iv seen and not a single Supercollider or Gorehowl.
Im not saying they changed things up, but you rly dont seem to get many weapons offered during the draft.
