Does the melee + X trait work different in Acadamy than in Arena?

Is it just wrong wording in the rules, or is the melee + X trait less powerful in Academy than in Arena? The arena rules say you only get to roll the extra dice during the first roll of an attack action. (Think sweeping or triple strike) The Academy rules say you only get to roll the extra dice the first roll during the same round. Is this correct? This will matter if, for example, you have a guard marker on a creature, and that marker was placed during the previous round. Then the creature will be able to (theoretically) make 2 attacks (different attack actions), this round.

So, in arena you may apply the melee + X twice during the same game round, but in Acadamy, only once. Is this correct?

I also wonder about the damage barriers. On OCTGN, people I have played with, think that the damage barrier should attack the same creature once each attack action. The rules say the damage barrier attacks the same creature only once each round. I think the first one makes more sense, but which one is correct?

Thanks in advance!

The academy rules are not wrong. We wanted to avoid some of the nuances of "melee +X" by making it a once per round thing.

Thank you! That sounds fair! Combos like Packleader's Cowl + Giant size would probably be a bit to much otherwise.
