Rakan/Xayah added in synergy is gimmicky and limits the potential of Rakan himself.
Rakan is an amazing champion design. he's mobile with clear upsides and downsides and a poor lane phase to go with a monster mid game/roam/pick potential. He's also fun as hell to play.
but he's gimped without Xayah. he can't dash as far, but with Xayah his ability to make full screen big time plays is HUGE. there needs to be a middle ground and their gimmicky forced synergy removed. (except for the sync'd recall.)
I'm sure it was intended for Rakan's dash bonus to xayah to not be a big deal, but it IS. its what makes him good.
look at the pro matches so far as well. Xayah/Rakan go together. but if Xayah is banned teams do not go for Rakan as by himself he is not great, but teams are still willing to play Xayah without Rakan.
its because of the useless gimmick tied to their couple lore. please remove it and just keep the sync'd recall which has way less gameplay impact.
having him have the same dash distance with all champs will allow him to be properly buffed around that rather than be hideously op with xayah in terms of engage threat and mediocre without her.
