medusa may not be good for a competitive carry, but for pubs shes great.
that mana shield and stone gaze is ridiculous, linkens and shes impossible to kill.
shes never was a bala or lycan type carry, but allow her time to farm that perseverance and its gg.
shes pretty useless as a support in the big scheme of things, great support inlane, with her range and mana steal snake thing, but if she hasnt got any farm, shes useless in a battle, might as well throw in a snake, run away and spend the rest of the game planting wards.
