Sona....where do we go from here

So i will admit, the movement speed boost is HUGE. The fact that the movement speed actually matters now, does so much for Sona. With that said, i'd still really like to see some more early game buffs. Buffing her... buffs.... (specifically her damage bonus buff) would likely go a long way into making her a more viable support early, without falling into the trap of just making her just another glass cannon mage support (but without the hard CC). I'd also still love song of celerity to give allies an "empowered" attack that debuffs the enemy. I think something like grounding effect would go a long way in helping Sona set up kills, without having to give her a "spam-able" form of hard CC.
