Please remove the double stacking of Senna passive from ARAM

I understand that ARAM is supposed to be accelerated, but it's already accelerated because of all the kills that are happening..

But Senna getting over 160 stacks in less than 15 minutes and out range turrets is just outright ridiculously broken. Not to mention all the other free stats that she's getting while constantly self sustaining. Kinda goes against the limitation that every other champion has to deal with.. Even Ornn passive is nerfed in ARAM, so why is Senna boosted when the passive is already very good if there's lot of constant team fighting?
