He isn't talking so much about campaign rewards because that got changed and increased. He is more talking how ppl would sit idle hitting the mobs to skill up. Or sit idle to skill up on the forts. It was changed due to ppl being low level afk and hitting the forts. Now you need to participate more to get more exp/points out of it. More so defeating the enemy then the fort. And it was unbalanced in the past people got more exp in attacking then defending. So forts were left w/o defences.
