I have no idea why Riot doesnt do these but oh well.
So Rakan and Xayah just got released and im not gonna pretend i know what the hell im doing so here is a helpful Megathread for you guys to discuss masteries/keystones/runes, Buildpath, Skill Order, normal old tips, ETC.
Share your knowledge.
Sarutobi2 votesDid you not watch the Spotlight they make for basically every champion before they are released? They usually share info like the ones you want.
That or play vs AI, Customs, Normals and test everything out. Everyone is new to these champions and are learning just as you. it takes time for people to understand a brand new champion!
Skorch1 votesNo offense but that is a very ignorant comment. This is a Megathread, sometimes things are hard to figure out, so you have other people bounce ideas and reasoning back at you. Not only that but you DO NOT learn everything in champion spotlights, thats why they are spotlights.
The point of this thread is to discuss which Keystone is best, wether AD or AP or Tank runes work better, Eye of the Oasis or Talisman and sightstone. Things that arent simple to figure out without outside perspective.

Koishi Komeiji1 votesLol, im trying from yesterday to play Xayah but she gets banned in ranked/draft and in blind someone instalocks everytime. I managed to pick her once and someone dodged. Havent played yet, good stuff.
lilpokfluf1 votesI played xayah once so far. Took standard adc runes and warlords bloodlust. I maxed Q and rushed bork. Waveclear was good but I don't think bork rush works well with Q max, maybe anyone that wishes to max Q for waveclear get a bf item first??. Possibly maxing W with bork would be better since they synergize better I think. i haven't tried with early bf but I think it might be a better burst but trade off the sustain from no bork rush. Fun champion though, reminds me of taliyah .
Skorch1 votesFrom what i have seen is its 
> Attack Speed Crit item > 
or something like that. And i wanna say E max. Not sure i play Rakan but eh.
Oh and i saw someone take TLD on Xayah and it worked REALLY well.
MissingKayo1 votesXayah is Fervor (18/0/12) Rakan is Windspeaker's. (0/18/12)
Xayah key items are BOTRK, Runaan's, potential Ghostblade, and some Zeal items. Rakan key items are probably Medallion into Redemption and Locket as usual, Ardent Censer.
Xayah would be Heal/Flash. Rakan would be Exhaust/Flash, but Ghost or Cleanse/Flash could also work in an easier matchup potentially.
Xayah first 3 is W->Q->E. Max order would be Q->E->W most likely, although max W second is good too. Rakan first 3 would probably be Q->E->W. Max order would be Q->E->W most likely as well.
Xayah can Flash during the untargetability in her ultimate to extend her range and catch people off guard or escape easier.
Rakan R engage into his W, Xayah R and E root will nuke most health for non tanky champions, and Q-W-autoattack barrage will finish off anyone else left.
Pre-6, Rakan W into Xayah Q-auto-E-shared W autoattack barrage.
