Offtopic: Why would you open such a topic on Best and Worst games forum? OT: I never liked Tristana, but if I had to chose, I'd go for the AD one. Her range and attack speed from Q in late is insane. I wouldn't underestimate AP one too, she can basically oneshot anyone.
Tristana is op whatever you play... But watch out, if you go mid and kata,lb,akali.. comes on you, you are going to lose
Look. AD tristana is good. But, i think AP tristana is better than AD tristana. If you have 100 abilitiy power on tristana, with your ult you will eat enemy adc or mid lane champion. I think is better to play tristana AP on mid lane. Good luck.
Well tristana's W,E,R are AP magic so i prefer playing her AP on mid she is very simillar to LeBlanc u can insta-kill an ADC, and her W refreshes after kill wich is nice for escape or going for double. AD Tristana is very weak early game almost all ADC counter her, but she is very good late game becuase of her passive and Q.
I think its better AD he has big dmg with blood/infinity but she is also good with AP rabadon/lich bane
