Learn Champions before Ranked

Please, take the time to actually learn a champion before you take them into ranked. Or you will cost your whole team LP. Take the time to read the abilities. look up videos of people playing the champions at higher elo see what they do and practice it. For example my last ranked game I had a cho'gath top that only, and I mean only used his ult for champions. it only killed like 5 people or cho with his ult in a 32 min game. in 32 mins he only had 5 stacks. while an average cho player that actually knows how to use the champion would have like 15 or more depending on his items. I told the guy to use his ult on minions, and I was a cho'gath main for a long time, and he said I don't know the champion his ult is on to long of a cd. For you guys that don't know cho'gath can ult 6 minions or something like that. but he gets really tanky from those minions. so if you only ult champions your going to be squishy af the for whole game. compared if you were to use your ult correctly and eat minions and ect. and your ult scales on your health. so if you use your ult correctly by eating minions you gain more health, get more tanky AND your ults damage goes up allowing you to kill champions easier than you just being a idiot and using it only to kill champions. So please save your LP and others LP and learn the champion before you play them. and I mean actually learn the champion
