Ana still needs something to mitigate the fact that she has too many hard counters and is easily shut down by D.VA, Winston, Genji, Tracer, Doomfist or Sombra — dive.
At the moment she’s a hero with too many hard counters whose forced to hug her Tanks to survive and can’t really operate at range.
The DEVs already stated that they’re wont on giving her a wall climb or self heal. Her lack of mobility and weak self heal is supposed to be her weakness. Her only self defense is a dart that’s harder to land than her own regular shots and is easily broken by stray damage.
The only thing I can think of that won’t upset her current play style and limitations is to perhaps finally give her a passive that’ll let her operate at range; past the distances she’s likely to get a peel — a Ghillie Suit.
It gives Ana two different and mutually exclusive play styles — close in as it is now where she relies on the protection of her team to survive or further out where she must change locations regularly or risk being located and killed.
Given her limitations this might give her the survival edge she needs — even in games where her own crew won’t baby sit her.
DEVs if you do go for this, can we also get a Ghillie Suit skin for Ana to go with it? It’ll go very far on differentiating Ana as a completely different type of sniper than Widowmaker. One prefers the high ground of the sniper’s nest to shoot from and the other is that far off distant hard to see tree or bush.
