difficulty scales with number of covers to avoid exploits

Jedam

Hello,

I'm playing simulator hard right now, and to be honest it's more like simulator hell. The lowest team is 125 while my better characters are lvl 140
Yet, with only half the nodes played, and only once, I'm ranked 11th with 2970 points. So I looked a top ranked, and the first has 9720 points, TWICE as much as the 2nd. So I checked his rooster : 58 character (4*, 3*, 2*) at level 104 or 94, WHEREAS they are fully covered.
Clearly he is exploiting a flaw in the system which allows him to have 58 characters to play with against an a.i that scales with level, whereas regular people like me have 10-15 characters to play with

Is the game intented to be like this ? cause in most (all) games, the stronger your character is, the easier the game is

This should be fixed as it is clearly an exploit.
I'm not sure how exactly the difficulty scales, but clearly it should take into account levels and covers

thanks
