When Zed hits you , you have a few moments to reposition and decide what to do next. Zoe hits bubble you can flash or try to reposition. Fizz hits ult you have a moment to react before it applies. Diana legit just jumps on you and you die. Talon goes invisible so you can be like oh fuck Imma leave. Diana is just a tactical nuke with zero counterplay when she is played correctly. You literally can not react fast enough.
PhDs Nuts3 votesDiana can't kill you without landing a Q first unless she's like 5 levels and 3 items ahead with a Lich Bane.
KuraSei1 votesAnd? Q is super easy to land
Alex h87212 votesyou mis-spelled

Killing you easily , with no counter play, and assassin mains will keep complaining about the bot lane meta because they can't freakin 1 vs 2 against a Kog and Lulu who would will w him , ffs I hate this meta
mages are free kills , whenever a jungler needs a free kill , just dive mid and that's it.
MysticDreams121 votesNah. She's fine to me, and has counterplay. All those you mentioned, besides Zoe, have one thing in common- escapes.
Diana has none, unless you call her using an ult on a minion to get out, but if she went all in, then her ult is on CD so that's useless.
Just stay away from her Q, easy enough. Build mr as well.
Easy peasy.
