Benefiting the game and making things easier for players are two different things and are often opposed to other another. Although, in this case, Wizards are receiving an upgrade to fade. Maybe that's why I like the change? The idea that Wizard AA nukes should be free because it's the only damage we can do once we're out of mana is something I disagree with. If anything, that concept was the mistake. It may have made a little bit of sense in old expansions but it no longer does in today's. It would be completely unacceptable for me to do nothing but hit AA nukes during a raid. I'd rather go back to guild hall and sit in the pool for two minutes and come back. Because of the limits on the number of AAs we can have it makes even more sense that they aren't going with the fixed cost approach and upgrading fade every 5 levels to update the costs accordingly. One AA to purchase is plenty. At level 85 it works on level 90 mobs and at level 115 it works on 120 mobs. That's increasing in power as you level. There's no way to twist that into what you're suggesting.
