Soraka plays like the Medic now in lane
Strategy for medic: heal all allies. prioritizing high value targets that are the lowest. Never let Heavy die unless he stoopid. If your health is low, hang back and watch as your amazing personal health regen heals you up to full in seconds.
Strategy for Soraka in lane: heal all allies, prioritizing high value targets that are the lowest. Never let your carry die unless they are bronzies who can't position worth shit. If your health is low, you can either Q the enemy for massive healing or you can hang back and let your high hps heal you up marginally slower but infinitely safer.
Oh she also has top tier disengage with E -> Q combo.
