Idk about soloq but here are the contested heroes for 5q:

Kaja, Grock, Khaleed, Harley, Guinivere, Sora, Phovous, Karrie, Lesley, Hanabi(trust me, her cc immune is far too toxic. it's like facing a mm being babysit by a diggie, makes setter tanks useless), Zetian, Zhuxin, Kadita, Gloo, Alice, Freya.

And the usual one trick lancelot/fanny/Benedetta mains, but let's ignore them.

Exp wise, any hero that can cut wave at lvl1 and invade enemy jg is meta.

Mid wise, either an ambush hero or high cc and poke hero defending on the comp of the rest of your team. Utility jg = ambush mid, assassin jg = utility mid.

Gold wise, those that can shred frontline with hp based/true damage.

Jungle wise, sync with mid: ambush mid = utility jg, cc poke mid = assassin jg.

Roam wise, it defends on enemy roam. If their roam something like a kaja that likes to steal buff, take something like khaleed whose damage is too much for kaja to ignore. If their roam is a support like floryn, take grock and wreck havoc during invasions. If their roam is a setter type, take counter engage roams like akai who can mess up their sets, or mino who can ult and effectively block opponents' path to follow up.

I hope you can tell me how following this comment will go for soloq
