Qiyana Thoughts

Just some thoughts on her, i don't think she needs any straight buffs because she's very hard to play but there are a couple glaring issues i have with her and the role she's supposed to play.
Weaknesses and Problem's I'v Run Into.
-
She losses lane in mid lane pretty easily, as an Assassin this is pretty bad, there are some Assassins such as Katarina, Akali or Fizz who have to wait for their Level 6 to be able to win 1v1's against other champions, depending on the match up but Qiyana will straight lose her lane match up's until she starts getting items, meaning that she has to Scale. Assassins don't Scale, they take over early and mid game and because Qiyana losses so easily mid lane, she has trouble in her primary Solo Lane.
-
Her W has an On-hit passive that i think is pretty unnecessary and that same passive is leading people to build her as a Bruiser/Tank instead of an assassin. Riot, you should know by now that you can't give Assassins reliable on-hit damage, just look at Ekko and Fizz. To add to this, none of her abilities count as Auto Attack reset, so you can't even really use it that well on her as Bruiser nor can you use her as a bruiser well at all since if you build, say, tri-force on her, she has a hard time getting the procs off while also being able to perform her Combo's properly.
-
Her E is kind of annoying, i understand not wanting her to be Hyper mobile(like Akali) but because her E is a targeted ability it really hurts her ability to get out of a fight. Assassins need to have the Potential to get in and get out, there are plenty of ways to stop them from doing that and some champions admittedly do have "Get out of jail free cards" but most of them don't and the only reason they got out is because the enemy team let them get out. Qiyana lacks that potential because her E is targetted, so in many situations, if you go in, your just, in. Further incentive to build her bruiser because she has trouble getting out. If her E just let her dash in a direction the same distance she goes now, i think it would be a lot better.
Strength's and Thing's I Like
-
Versatility, this champion's got it. Her Q and W are awesome, i really don't understand why her W has to have an on-hit passive slapped on to it when she already has Three separate abilities on her Q. If they took away the on-hit on her W they might be able to put more power into her E instead, such as what i mentioned above.
-
Her Ultimate is honestly a bit too strong, i feel like her lack of ability to be a functional assassin except when she's incredibly fed comes from her R taking up a large portion of her Power Budget. Sure assassins should have to use their R to kill you but this thing is arguably one of the best AOE stun's in the game and that's really REALLY powerful to put on an assassin.
Tips and Tricks
-
Her Q will automatically target the target of her E, if you E and then the enemy flashes away as you arive and you press Q, it will track them without any input needed from you. This is super SUPER helpful with landing her Primary damage combo.

E+Q+W+Q
This is her Bread and Butter kill combo, but something you might not know is that you can do this combo in less than a second, it's kind of misleading how fast you think you can do it at first, but upon further practice you can just cut off the animation of her first Q with her W and immediately Q again. You can do this with any version of your Q in any order. Also, side note, using this combo with your River Q will make landing your second easy, since using your E nearly guarantee's you hit them, there's pretty much not counterplay to it once your on-top of them, even if they flash or dash away your Q will still try to follow them, so it's hard to avoid the first hit after the E.(Note: If you can get an Auto Attack in, go ahead but it's not necessary most of the time.)
- E+Flash+R or just E+R
This one is easy, it's the same concept as Azir, Gnar or Lee Sin. An issue i ran into while doing this though was that if i did it to early, Qiyana would frequently use her R in the direction she was facing, not the direction of my mouse, so it might take some practice but it's certainly doable and it's VERY strong if you hit a Wall(it also does a HUGE chunk of damage.)
You can also use this before your Q+W+Q combo and it deals A LOT of damage while also being really hard to dodge.
Finally, on the PBE Player created terrain such as Anivia's Wall or Taliyah's R did NOT interact with Qiyana's ultimate but they do now and that's pretty nice since you can have Azir Shurima shuffle a whole team into you and then R his Soldier Wall. Lot's of strong combo's with this one, i just hope some small Quality of Life changes are made to push her a lot closer to the Assassin side of the Spectrum.
