i find her to be the worst adc anyway... Range, yeah, its good, maybe.... but its always been a little heightened. if they even touch the range on her then she's useless. But if they touch her other spells then she isn't changed because... overall, they are pretty bad. The ult is medicore and can be blocked/ignored, the q is strong early but a negative influence late, the w is good but the e escape is confusing mostly and often too slow, and doesn't work like ezreals e or corkis w or trists w.
So idunno, its probably just fotm and will wash away in a week when people realise tristana does the exact same ****ing thing. (by people i mean tourneys or stuff.)
