Why are ADC's that can build ap a big thing mid now?

Technically, every champions could be played in any position. It's just a matter of optimal or not. As of the current meta, bursty assassins, although still popular, are not as dominant as they once were due to the tank meta being in force and assassins have hard time fighting against them. Poking Champion are more suitable now as they are easier to reach the back line from a distance. A Varus Q, a Kogmaw R, an Azir W-Q, etc are all skills that can reach the back line easily without the need to jump pass the tank line.

Varus and Kog'maw are big now because of their insane poke game. I've seen Sivirs blow E and R just to get away from Kog'maw poke, and Varus poke is nearly as good. You can siege insanely well as these champions, as nobody wants to get near enough to contest the tower. Any questions?

Varus actually builds AD even when he goes mid. He usually goes Manamune > Youmuu's > LW.

Don't think of a champion as an ADC. The champion is played traditionally as an ADC, but no champion is restricted to a role, some can be built bruiser, AD caster, AP caster and have a lot of success.

ADC's that can be play mid as AP:

Though you could play as AP in the mid lane but they're better off AD.

It's a tank meta, and burst assassins have been a bit nerfed. AP marksmen become thus viable on mid lane

I'm looking for some guys to play some games with nothing serious casual play. Feel free to add me if interested.

Its not that they are adc or ap its poke/ range and utility

Only ezreal is what I've been seeing

I had a post about this before, and in general the answers and my understanding is this:

ADCs that are chosen mid lane are generally safer than most mid lane, EZ = E+ flash Kogmaw = 4 screens away Varus = 2 screens away lol^ these champions can put out tons of damage from a safer distance

So risk/reward ratio vs something like viktor that can get 1 shotted just as fast as he can 1 shot someone because of his range.

There was also an example of this in the GMB vs SK game, Cassio just couldn't do any damage safely, where as varus could and the impact was CLEARLY visible.

I am Kogmaw main and the other team has to have very good coordination and a specific comp to ever take me down check out my match history lol

Example? I haven't really seen this.
