*Thinks: Is this true?*
Sure, more non-americans are ranked highly on the ladder right now, I'm pointing out when I was around we had a USA League that had like maybe 12 members, maybe 2 could've been considered top players at the time.
Now I can think of a lot of very good players that are American, that don't really show up often in the ladders.
Starting with the dudes in Master:
MotD
Atom
Turtle
Jz
Miyagi
TWM (If he shakes off the rust)
and the guys in Blitz they have/will pick up.
In Apex:
Myself
Beren
NoobSchool (has progressed so much since that time, though he can't be very active anymore)
In WG:
Falker
ChrisCMU (progressed a lot since that time)
Oh Noes
In GG:
EZPickens
JSA's Bro
There's a lot more people who are developing in like Illuminati, Turtles, etc. there's a lot more top Americans than was the case.
