Carrying as ADC - OTP vs Situational I'm currently climbing elo and eventually would like to get to diamond this season, Currently in G3. My most played champion is Draven and I've played him since season 3 and got up to plat the last two seasons. 

A lot of people say to pick one champion and grind them every game but does it also apply to ADCs? It seems that marksman are mostly straightforward and there isn't TOO much of a difference between them. I'm considering if I should keep grinding draven games or have a larger adc pool and pick based around compositions?
