How to deal with Lina as a midlaner?

Hey, I am a 7k MMR player who just got back to playing after not playing for a few months, and now Lina is everywhere, she is very strong but I kind of don't know how to deal with her?
Her lane has always been very strong but most people are playing her more aggressively than usual and it is really hard to deal with, then she gets Travels and Aghs and she is a beast around the map, very hard to follow her, she still farms extremely fast (probably even faster with the magic build), and then she just deals a ton of damage and is really hard to catch. Anyway the hero is extremely strong early and mid game, is she just busted or am I just bad?

Also is the Gleipnir right-click build just dead? I really enjoyed playing it and I feel like it was more of a 1v9 style which is closer to the other heroes I play.
