why does drow feel so much weaker rn?

this is just a personal experience, but I'm wondering why drow feels weaker rn? drow is always my safe pick if idk what to pick and against melee heroes in lane just feels good. if i can pair it with melee 5 it's just heaven for me, but

basically i harass well in lane, and last hit ok. early levels feels hard but after some stats it's ez. if lane goes bad i can always farm fast enough with a clarity and 2 wb and actually join fights with d lance. that all seems the same still but when it goes to mid to late game her dmg seems less now for me even tho i build silver edge butter? is my build bad or what

i buy pike first then shard and then bkb/manta/linken depending on how enemy heroes are. silver edge butter and if i need skadi/satanic and end up with swift blink to replace boots. it all feels good enough until enemies buy like 10 green armour which previously was not as bad it felt like but now someone with 10 green armour and 3k hp feels so hard to kill
