while some lanes you can win if you are good enough other lanes are just complete loses
Example
players will often freak out if they see
but as a ahri player i can tell you that match up is so over hyped and a good ahri player can win it easily if they remember their two core advantages
-Poke range for harass
-Charm to cancel his ult
But if you forget those two things than yeah zed is gonna win it. Other match ups like
vs
+
than yeah your lane phase is doomed, and unless the pantheon is the worlds biggest fucking idiot. You really have no hope of winning that lane, even if your jungler helps you out, it will be extremely hard to win. The best you can do is get the cs he allows you, roam when you can and make a strategy for when laning phase is over.
