there is competitive very shortly.thats why you rank up in public arcade and unranked.once you get to level 10 when its added you can then go play competitive.
public servers are easy.its just like any other fps title in that regards.any medium skilled people will win most games pretty easy.the difference is when you playing in games where everyone else is med plus or high then obviously it isnt easy as your skill level will be the lowest in the game.so you either have to play very well the whole game to finish level par or out your skin to win.that is the difference.
there are pros playing it but you probably havent played against any yet.there was some pro tournes last night. you may think there is a small learning curve which is pretty true for public arcade play.once you in higher ranked or competitive play see how far that gets you
you could be a great player in general for all i know but saying there is little to learn kinda points to the other.
you need to know the map layouts.
you need to know the key points of attack.
nade spots.
jump spots.
best routes to and from objectives.
which are best guns and how they work best.
you havent figured that out in one week.
leave this till late then we will see in ranked play.
