You can train any skill however high you want but in the game it only goes up to 340
There is no official words from Nordeus but it is how it work
The sad thing is it is not official and guys not watching the board may train their FK to 500 and wasting their resource
Players already went over 340 is now handycapped to 340 so your actual star rating is lower
And all this without official announcement, all done behind our backs to sastify the free riding whiners
