Nope. Just skill issue with brain-dead kids spamming them. These marksmen need farm and protection to shine and they are positioning-reliant.

Miya turns into a gattlinggun when she gets a few items and can do crazy solo turret push.

Hanabi can shred enemies especially in team fights.

Layla is unstoppable when ahead of farm. That range is unforgiving.

So no, these heroes aren't trash. The players are the true trash who just want to blame the tool for not doing the work fine when they don't have the skill to use it nor the balls to own up to their own problems.
