A sona change

I feel like sona is a little weak in most regards but it is because she has everything a support has/wants poke,heal,movement speed and really strong lvl 6 cc, but i feel like none of them are strong enough to justify all the nerf she has got as of recently. So i came up with a small idea of making her into a combo mage "as she mostly is now" but not in the way of just mash q then land power cord more of a photo i made with my poor drawing skills

the whole plan i hade behind it was too have it so her aura ranges went as she combo her spells the first in blue second in green and 3rd in purple the yellow being after she ults all of her auras are mixed for the next 3-5 seconds and can not be kept up by using other spells and if your not on your 3rd stack of auras it will be moved to the next stack in the list "as in if you are only q+w to the second one you can ult and not w and only go to the purple but it will still give the aura for q+w" i feel as if this will not take sona's identity while fitting into her music theme if you have anything to say let me know i just made this because i was board and through it sounded fun :D
