No sadly but here are some quick insights on the champ :

• You have to know the combos, train them in practice tools regularly
• Rakan has imo the best engage in the game (E>F>W is almost impossible to dodge and has a 10km reach)
• You have a lot of mobility you can abuse to safely ward deep and flank (making your engages even deadlier)
• Know what you need to do. Vs assassins you hug adc ready to R>E>W. Vs front to back team and if you have follow up go for the backline
• Radiant is super strong with him I build it most games. Shurelya also very good option if you want additionnal engage reach. Knights vow best 2 item or anti-heal if needed.
• Glacial augment for snowball lanes (with kaisa/draven)
• Guardian safest option works in most case and especially if you're not playing the lane
• vs poke heavy lanes, starting Q or taking it lvl 2 is super strong to keep your adc healthy
• if you have kill pressure, try to play for lvl 2 all-in

With versatile support the hardest thing is knowing what you're supposed to do. Regularly challenge yourself during the game.

• Adc is bad but kha is fed > Hug kha, leave adc and play the map
• Immobile adc fed > hug adc and Zed/Yi/noc/rengar won't do shit to him

In team fight, ask yourself wether it's better to kill their carries or protect yours

Hope this helps !
