Perks

Friends, what perks do you take and what is the reasoning behind them? My thought process is : sleepdart slow vs 0 dashes heroes OR if nano movespeed won't do much for my targets. If i have a Ram/Rein is always movespeed regardless of enemy dashes, they just turn into monsters. Grenade bounce - headshot : grenade bounce into hog/mauga since it's crucial to land those nades and this perk give me a 2nd chance if i miss OR if i'm stuck healbotting because teammates refuse to stop taking damage. Headshot perk only if i feel like i can reliably hit enemy heroes or i have a really good tank that makes space for me. I do love the headshot perk and the kill potential it gives but I mostly feel like it's the "win-more" perk. Any tips on the thought process would be greatly appreciated. Elo is gold-silver
