what's her tradeoff? she outdamages other supports that aren't brand or velkoz, outheals everyone that isn't named soraka(and in some cases even her)while also dealing damage, has a better version of karma's mantra e(senna has a longer cd but who cares, she can shield the whole team easily while damaging the whole enemy team), and has decent range even before her passive kicks in. like for real. she might be fun, but she is pure cancer to lane against unless you run an all in support. the fact that she just came out and is sitting at a 50% winrate should tell you something. that something being that she's way too easy to pick up and win despite not having much practice with her.
