lol, squad battle rewards are far from bad and they easiest to optain.
u dont even have to play all 40 games if u not completely bad.
about 45k points usually enough for elite 1 and u get 2 rare mega packs and 30(?)k coins without any pressure or stress.
in wl/rivals u need to get atleast gold 1/div 3 to get better rewards where u gotta play more games, more stress and gotta put up with tryharding and defending with 10 man
