Sooooo in ranked play u dont want to only focus kills,u have one of best ultimates for roaming and focusing objectivs like TF (but is not better then Tf ult)

In teamfight u want to be in midlle of fights cuz you are midlle range mage and also with this build you are pretty much at 2900 hp in late game,soo you are tanky too,try to focus squishy targets or if you are having a bad time and u are feeding try to peel for your teammates

W and E - After taliyah patch u can use W(knock up in any direction) almost freely,soo that means doing E+W (with E you place boulders in front of you,they props on any interactions across them besides normal walking or blink spells) combo is not soo akward now,for example try to W enemy closer to you and when your W is about to hit throw E right after your W(E+W,you can still use it but enemy will expect u are going to W him so he will dodge, i prefer W+E for suprising the enemy)

Q(throwing 5 rocks,if is there circle after using Q alerady shoots only one q and give you back of 50% mana and you can move freely like with lucian ult) - best for poking enemy or farming,and is it one of yours main damages cuz it have the lowest CD

R(you make a wall that you ride(if u press R 2 times u ride it),and if somebody hits you when you ride your ult,your down from it but the wall continue) - try to roam and cut your oponents or take objectives,or stop enemy from doing objectives

Just farm with your Q,it is pretty easy,just try to throw one Q at the time to farm or decrease minions hp to last hit it with aa.(you can also use W+E for more clear but that takes a lot of mana early,and that W can save u from gank so keep it on cd)

in summary this is my favorite champ and i love her and her play style,its a little bit tanky and bursty mage,and the reason why i made this guide is get you in mood for taliyah and try her out to see how op she actually is.hope you enjoyed my hard work and learned something new ^_^,bye and GL to your Ranked Games-Tom3wars
