Riot, Old Soraka, + more

Lets start this off positive:

Riot, since the announcement of the game mode rotation, would it be possible to include a legacy mode? This would feature the temporary comeback of pre-reworked champions. Like Soraka with old starcall and mana refill or pre-rework Sion.

Soraka:

Before Soraka's most recent big rework, she was by far my favorite champion in the game. Being able to refill mana, the heal was a lot of fun despite it's gigantic cooldown, and my all time favorite ability in the game which is Soraka's old starcall. At the time she was not favorable to play as a support but it was very possible to go on long win streaks with that pick with the right build.

Would it be possible to at least bring back old starcall and just reduce the numbers? Maybe just reduce the MR shred if you feel it was too much or reduce the damage dealt. I want my old starcall back :(. I wouldn't mind having the old heal back either. A big heal with a long cooldown that doesn't cost health does not seem that OP to me. Her E is where a lot of her super strength came from. Being able to point and click silence people at no mana cost or refill mana on your teammate at no mana cost to yourself. You did later address that though by continuously increasing the mana cost on that ability until most people saw her as unplayable in the support role.

Seeing all of the wild and crazy Soraka changes to her current kit is just driving me mad. Just bring back parts of her old kit please. I beg of you.
