Is ambessa broken or is eclipse just too good?

Characters with overloaded kits like ambessa with a lot of mobility and run down potential (Eg riven, akali) tend to have a pretty high skill floor or at least have been historicallyhard characters to pick up for lower elo players which generally makes for these characters to be sub 50% winrate characters in these elo brackets.

However current stats show that other characters that use this item such as riven or aatrox are also over 50% wr characters in these elos which is not a usual thing at least up to what i know (Correct me if im wrong).

Having all of this at account what are your overall thoughts on ambessa and do yall believe that riot should wait to hit eclipse with nerfs before hiting ambessa directly or should both be hit?
