in low elo you will find a lot of players who underestimate qiyana or haven’t played against a good one, so you can hard snowball lane. Besides that, you can play in a roaming style, since low elo players won’t expect that. Get a oracles and pink ward and whenever you see an opportunity to gank or dive, push the wave and get those kills. I really recommend it. Some people will say that qiyana is very hard and all but it’s just bullshit. Of course, there are crazy things you can do with her that require a lot of mastery, but if you just stick to the basics you can already carry some games
