Qiyana's gameplay is so boring

She just spams whichever Q is the best for the situation. It's a short cooldown and not very difficult to decide which one to use. If you miss it, don't worry its up again in a couple of seconds. If you get someone low, then you can just go for the E-Q combo and instant aim to kill them easy too.

Her entire gameplay revolves around just spamming ranged Q, and if you finally get them low enough, you go for the kill. She never has to be in a risky position to whittle down the enemy. There's just very little decision making in her gameplay and it's just really uninteresting.

Some things that could be done to change it up would be to change the type of attack indicator depending on which element she has. For instance, keep her wall one the same, make the river one like a nami bubble (circle aoe), and make grass like zyra Q. There now she has different choices in how she wants to try to hit her enemies, and for her enemies to play around avoiding being hit. The different elements could even be different cast speeds to change up the timing for hitting opponents. That was just the first thing off the top of my head and probably not optimized, but it's to give an idea of what I mean.
