Can we get some Taliyah adjustments?

I feel like right now Taliyah is in a really weird spot. Her utility and damage are really on-par but her mana costs are just... ridiculous. By level 18, every single ability on her costs 100 mana or more. I've been trying to cope with these nerfs for about a month now, but it just feels so awful to run out of mana instantly without blue buff.

Can we get some healthier adjustments for her kit? I seriously do not mind doing the following: -sacrificing some damage and increasing the CD on her Q if it means I can use it fluently with a lower mana cost. -slightly decreasing her mana costs on her Q, W, and E while sacrificing damage on each ability. I am by no means asking for buffs.... just adjustments. Running out of mana so quickly is really common for her if you don't buy atleast 2 huge mana boosting items. But on a champion that is supposed to be an early-mid game dominant champ, it's really weird... she's not an anivia or ryze... Any other suggestions?
