Most of them play long enough to have seen nearly everything possible
It is nice to get that high into the ranks, but you will have the one or other lost, too.
Hardly a player gets one or more week done without loosing the one or other duell.
Some use this to do some tuning on their mechs, depending on the popular setup played most.
Others just keep on playing
When you allready got there, you made a lot in a perfect way.
But the one thing you should always remember, is:

It is just a game!

Now you could say: who are you to tell me this!
I am a no money player, no special rank for now.
I play for fun, sometimes I win, sometimes I loose!
But I try to keep my fun.
Never forget: YOU can beat about 99% of all players!
You will be fine
