Expert take
Soraka is an excellent choice for players who can read a fight before it explodes. She does not only require fast healing reactions: she requires understanding who is about to be hit, which enemy spell truly threatens the backline, and when the ultimate changes the result of a fight instead of merely delaying a death. She shines when her team agrees to play around her range and presence, not when everyone looks for individual plays. Played well, Soraka makes the enemy feel permanently one spell or one second short of finishing kills. Played poorly, she becomes a fragile support who heals too late and gets punished as soon as the fight becomes direct.
