They say it's better because it has the ability to deal 1.5 damage to an enemy standing on an adjacent tile without retaliation... But I'm a bit confused. First, they removed the antimagic ability, and second, on the first turn, you still have to fly to the enemy, so you won't be able to use the ability (there's no enemy on adjacent tiles), and after the second hit from the Death Dragon, you're unlikely to get significant retaliation... :-) and Dragon's Breath deals double damage (you can hit 2 units), while burning deals 1.5, and the red one has fewer hit points, and its damage is also lower...
