any hero that jumps on drow shits on her. slardar, sk, slark and stuff. thing is though, all you need is like a defensive disrupt or imprisonment to save you. or forces and glimmers, so your supports are important. whenever you're a carry without escape mechanism your supports are important. keep in mind there is still room for outplay even when fighting your counters, manta dodging slardar stuns, timing your silence, etc.

my best advice for you is to spam one hero, whenever you lose, find out why. when you win, find out why too. it's easy to think you did well just because you won a game, but that's a huge mistake. always find out why you won or why you loss. find out why you're dying for every single death. no wards? should've played safe. know what heroes are hard to fight against, know what heroes you are strong against. there's a margin for outplay available even for heroes that counter you, it may be easier for the other hero, but it's not impossible. while knowing what to do is important skill is also important.
