理由
Karma puts you behind through tempo: poke, shield, speed, and priority. Soraka wants a stable lane to breathe for Q and manage mana. Karma removes that stability and forces W as a constant band-aid, which is never good economy.
レーン戦への影響
In lane, you get shoved and sit under tower, ward less, and play more blind. If you try to trade back, you step into punish range; if you don’t, your ADC loses lane. At first dragon, Karma often arrives with better resources.
立ち回り方
Positioning: play closer to turret when jungle info is missing, and use defensive bushes to break poke lines. Timing: level 5 is your first real turn tool—until then, preserve HP/mana. Decision: if Karma owns prio, accept it and focus on ‘arrive OK for dragon’: clean reset, early wards with jungler, and no solo attempts to reclaim river.
