i play 1s mainly for a few reasons 1. i dont have to blame teammates if i get scored on its because i messed up 2. you learn to be consistent quicker and rely on yourself to do better 3. 1s is the hardest mode imo by gameplay and if you get high there if you wanna run something else you have all that experience and can take it somewhere else 4. ive just always been a ones main im diamond 2 division 3 (903 mmr) on a 6 game streak and im just consistent with it
