Darius mah boy.
Lux is also quite intreguing.
Though I've failed to understand why Darius is very rarely played these days..
Darius has nothing to offer that could be helpful for a team in an organized (LCS, LCK, etc.) teamfight.
Fighters in the top lane died out when the tp cd on a turret got introduced.
Tanks just need to play save and come back to lane/make plays bot with tp until they are the tank their teams need.
It is true Darius is a lane bully in soloq. I am sure somebody who mains Darius knows his sh!t and can climb high because of the high snowball potential he has in unorganized games.
Meanwhile in the LCS, it is so easy to shut a specific champion down if the team really wants to do so. Darius has no mobility, no gap closers, no (natural) tankiness, no cc, and has either no damage (if build tanky) or no tankiness (if build full damage). Besides it is so easy to kite and poke him because he has no kind of engage.
This is probably the reason why other champs arent played that often as well.
Nasus, Riven, Fiora, Garen and much more.
