That happens with my brother he is now level 5
there is teams that had been there for 3 "Including level 5" season now.
I guess you might have added them as your friends. if you have a friend on the same server as you, you will be both at a competition either CL or League.
but my brother finds it cool as they are HEAVY players, with fatal squads last season he was a runner-up and won this one.
