Stereotype: a healer with some throughput (Brew), some pad (Serpent) and Blind, countering AA heroes. Possibly a troll.
Facts: her throughput is among the lowest, she lags behind most, if not all healers until 10, or rather 16, where double Q or percent-W comes alive. While she can troll effectively with the illusion of being out of position, the entire team just waiting to pounce on the pouncer, she can easily die in 1 second from any kind of pouncing (unless the team is to save her). Her Blind and Serpent attack heroes, therefore she cannot approach towers. Hence she is a backline healer.
Among her counters are: Butcher, Tracer, Tychus, Raynor, Falstad, Zul’jin, Valla.
(I checked this on Heroes Profile after a repeated experience of being wrecked by badly by these heroes.)
So, what’s her point now? I don’t recall any recent nerfs, although some above heroes have been buffed.
Last season I was okay with her still, but now I’m about 31% and while it could be attributed to my extreme lack of luck this season, including hard countered in QM and facing smurfs, her global winrate is 46.5%. My healer winrate is actually 48% so she is the worst - and that’s talking about low Silvers, where she is supposedly OP.
