Senna

Hey, so this is my first post ever, so pls don't be mean. Anyways, me and my friends have discussed some problems that we feel are with Senna and I would like this to be a sort of thing that Riot might look at I guess, I dunno, anyways. Her E(the shadow cloud wraith thing) seems way too good and should be completely changed into something not that good, which was the only thing me and my friends agreed on. I personally feel like her range should be reduced to the shortest ranged champion range since it can scale for the purposes of not being effectively the longest range after 20 stacks, and since my friend seems to have a problem with the ult, I thing it would be interesting if it was based off of attack range instead of just starting out global (like one rank is twice attack range, two is three times attack range, and three is four times attack range.). I think that this is all that would really need to be done to make her more a support oriented champ, but I'm not that good at the game and not a designer, so what do I know?
