It's nice to meet a team you already know, but if they implemented this then CL groups could only be drawn from 8 leagues. Maybe two from the same league could be drawn together
I'd like to see more than the 6 league winners that were drawn in my opening groups too, so maybe they could put 1&4 and 2&3 places together and draw from 16 leagues
Of course I'm low level so there are lots of leagues to draw teams from - July, I take it from your responses that you're not more likely to meet familiar teams further up the levels?
