I don't agree with this.
L2 against L13 never happens in the real world.
The FA cup as an example.
L2 is akin to NW counties or southern counties, 11 leagues apart is total rubbish.
To me it just shows how fragmented the servers are, with not enough leagues on certain servers to make them competitive.
When I was L2 all cup sides were L2, L3 was the same and this season, all L4 with 3 L2 and four L3.
By the time we reached the last 16 all are L4 and 1 L3.
The CL is all L4
Now that is more realistic.
