Janna should have to pay for her mobility
No one should get this free. Blitzcrank has to spend mana to chase people, and now you actually have time to punish him if he misses you. Meanwhile Janna gets free MS for herself and her team all game, and she has just as much CC as Blitzcrank. Anyways, this isn't about comparing Blitz to Janna. The point is that every support that gets a MS boost has to pay mana to use it or purchase mobility boots. Janna doesn't have to to this, and she offers more CC than most supports. Janna needs to have some sort of weakness, and I feel like right now she has none.
