While the hero powers are the same as with Justicar, the fact they are active from turn 1 rather than turn 6 (at earliest) makes a big difference for some classes.
Of particular note, no one used Justcar in rogue because by turn 6 you were usually damaged enough to not want to use the hero power much for attacking minions, but to have a 2 attack weapon in the early game might be a much bigger deal. Druid and mage would also benefit greatly from having the upgrade much earlier, as would paladin.
With the other classes i doubt there is much desire to use the hero power that much in the early game, so I expect them to be good or bad in much the same way as they were with Justicar (namely warrior and priest do well, the others less so).
good point on the early game difference
Warlock dont have an advantage of drawing without drawback ?
Face hunter would not gain more from the upgrade hero power ?
With Warlock you actually wanted to damage yourself due to cards like Molten Giant. And Justicar was just way to slow for how aggressive Face Hunter used to be back then and the one point of extra damage was not worth the tempo loss.
