New Support Concept: Scaling Energy/Giving Mana

Now I have always been wanting a support like this for the longest time possible. It might be hard to explain, but I will try my best. I want an Energy support that his or her main ability is to give mana. As every level he or she goes up her Energy regen goes up too. Like at level 3 they could have 245 energy and gain 34, and then at like level 6 they could have 290 energy and gain 45, peaking at like 470 energy. This is just a very plain concept right now because I just like the idea, and if I keep working hard I will work better with this concept. I hope you guys like it and if you want to add to it please do not be scared to put ideas in the comments down below!

How I got this idea: The main concept where I got this idea from is because I am a main support. There are no champs thats there main focus is to give mana, but most of them give health. You do not know how many times I wish I could give me ADC mana to push a lane rather then giving her health just to sick back and do nothing. I think this support would make bot lane be more full of action and it could be very fun. A way you could counter a support like that is getting a pushing adc, someone that clears lanes fast so that that adc would not be able to push back no matter how much mana they have.

Update: I have been putting a lot more work into this concept hoping to push it more foward.
