My One Issue with Rakan and Xayah

#I love the new champions

Thematically, they are amazing and look amazing. They both look fun to play and I wish to have both of them in my champion pool eventually. Then, where's my issue with them.

They function too well with each other.

Now the idea of having champions with synergy is awesome, and it's happened before with champions' kits working well together, such as and as well as and , but there may be specific issues with having champions with increased potential and power when they're working with another champion not because of synergy, but because of specific gameplay elements that only work when they are together. So far, when working together Rakan and Xayah gain:

• A paired recall, which can allow them to recall at the same time and causes one of them to not have to channel their recall. This is HUGE for a lane where the support and ADC may want to go back to lane together, and they can (technically) recall faster if they hop onto someone already recalling.
• Rakan gains an increased leap distance to Xayah when using his shield dash ability. This is also a really good synergy because it technically lets Rakan be more mobile.
• Xayah gives her W bonus to Rakan as well, giving the support some damage. This isn't as big a synergy, but I think instead of having it where Xayah's W works only on Rakan, make it so it can be cast on an ally to give her and the ally the bonus.

So because of their synergy Rakan and Xayah may end having problems if they become OP. They could end up only working well together and perform poorly solo, or end up not having a massive synergy with each other. I prefer the latter, while thematically having the champions work together is really cool, I feel that since Rakan's playstyle already benefits Xayah (Rakan can protect Xayah and CC opponents into her line of fire) they don't need massive synergy. I may be wrong about this, but that's just my thoughts on the situation. We'll have to wait until people test them to find out.

TL;DR: Rakan and Xayah's potentially amazing synergy with one another and weaker synergy with other champs may cause them to have balance issues in game. Other than that, love the champs.
