From what I've read already about her stats and ratios. Shes gona need a nerf or two if you want her to be a support champ. Her damage output potential is so damn high! with 2 hard CCs and a damage buff.
I love supports, and if she came out as is, holy moley,
I know that she is in the early phases of testing and only was just revealed, but Nami is likely gona get the same treatment as lulu when she was released; as a top AP or mid AP. (though with all these new items and item changes that i've seen, the meta is going to change. So maybe just everyone is going to be doing more damage)
Keep up the good work with the champion releases. Ill be getting her since shes labelled as a 'support' :P
