Taliyah's Problem and How to Fix Her

Initial data has Taliyah at around 37% so it seems likely buffs will occur. After playing her a few times my initial impressions are that her damage is astronomical pre 6 and respectable if nothing special later on. So why do a lot of people feel she does too litle? It's because of the riskiness inherent in her kit. The bulk of her damage comes from her we combo, which involves throwing someone INTO YOUR FACE or them already being there. This is fine in a midlane fight to the death or when ganking but results her in falling off a cliff mid to late game. She ends up relying pretty much entirely on long range q's which is less than effective. So how to solve this? Well, you could relegate her to a kill lane support who turns into an r bot late game but I was promised a midlane mage, which means she needs some scaling. Upping her damage would lead to her being overly binary, dealing enormous damage in those cases she can unload point blank while doing nothing for her horrible teamfight outside her ult. In my opinion the best way to improve her and make her more magey is to up her range. Adding another row of pebbles to e would make we less of a lategame deathwish; alternatively adding range to q would let her better transition into a lower damage poke role as she would have more room to find unworked ground.
