I didn't say that the Phoenix is weak. If it reaches the archers, they're done for. But when the opponent has, for example, 20 Titans and almost 40 Rakshasas, the Phoenix won't last long. And why are Dark Elves considered weak?! They have a small growth rate because they are strong. Assassins, for example, have fourteen hit points, which not every second-level unit has. Or Hydras. Or Minotaurs. Or Riders. They all have a lot of hit points, except for the Enchantresses.
