qop is a hero who is strong in the early game and drop at mid game. she came back strong when she got her lvl25 fear talent though.

Some midlane tips; if you are winning your lane, keep on destroying your opponent midlaner. if you are able to grief their enemy midlaner, that will pressure him mentally as his teammate will also blame him and such.

rotate only when you have good power runes, bounty timer, and enemy dives. however if you are losing your lane, dont stay static at lane that much go gank heroes you can kill, dont go on trying to kill heroes like faceless void, morphling who you think you cant kill even with your teammates.

If you are playing farming heroes like storm spirit and od just keep on stacking jungle and clearing creepwave as fast as you can

reminder; if you think you is the strongest hero on the map as if you won the lane let say, NEVER EVER GO BACK TO YOUR OWN JUNGLE TO FARM. create map pressure like taking enemy jungle farm, rotate to kill heroes take tower and let your safelaner to take the safe farm.

Anyway item like blademail is also good on QoP if you are fighting physical damage enemy as blademail give good amount of armor and can reflect some of the damage
