I think she is alright top lane against some bruisers as her kit is really good at kiting and screwing over melee bruisers not to mention most of them deal sustained damage so her R + W screws them over really hard
You're focusing too hard on her laning phase,most meta top laners(with tp) can out regen her mana(as in->eat shit->use some ability to heal/pots->eats some more shit->karma runs out of mana),and will outscale her hard,you could pick lulu/lissandra instead,have a rather similar laning and scale better into lategame.
She does have some strength in her versatility,as in she can lane(though will generally get outscaled) vs right about anything,right about anywhere,I do somewhat feel she has more room as a support(due to their early game focus) and as a mid,where she can bully her opponent and roam okayishly(though then again le broken and trashfox can do that better,and scale better),I think she could use some buffs(specifically,I think riot will have to concede the linear scaling of her ult,same as they did with renekton).
