I kind of agree, mostly because it makes balancing certain effects on neutral cards (like inspire) pretty much impossible, limiting design space.
Other than that I don't mind it being 1 mana. In fact I'm quite happy to see a vanilla hero power that's actually useful and gameplay-defining in modern Hearthstone, rather than just something you use when you have mana to spare and have no impact on how you build your deck or play the game (Priest, Druid, Paladin, etc).
