Can Rengar finally get old ferocity back (no diminishing + 5 stacks) and his old passive ???

Riot, can you bring back Rengar's old ferocity (no diminishing and 5 stacks, no gains from leaping). Also change the ult to what it was (still camouflage, now gives 5 ferocity stacks over the period of 3 s + gives bonus movement speed, no more bonus MS on using empowered abilities). Also bring back his old passive, no more bonus AD. Also bring back old W. That would be a full revert and it would probably be fine, but still be counterable.
