Awakening sorc does not have an input bound to S+E in the awakening skill tree, so it is a free addition that does not conflict with any other skill input.
for grinding in awakening it is intuitive to have this skill be S+E and be a transition skill, it is awkward to use skills from quickslot mid pve combo.
