I give up too easily on learning new champs
This usually happens within first 10 matches. I play with the new champs I just got, and unless I carry or be decent at the champ from the start, I drop on ever playing that champ again.
For example, I bought Olaf the other day because he looked badass and played badass on youtube and during matches. I lost the first 4 matches before refunding him. Then I bought Vi, whom I won 8/10 matches, and kept her around ever since.
My friend, who plays frequently with me always tells me "How can you become better at the champion if you don't play him/her?" I totally see his point, but if I feed 0/6 to a Hecairm to trolled by running down mid and Yasuo mid, I really don't see a point of playing Ahri.
Maybe it's because I suck at certain lanes or the champs who are on the higher skill ratings?
Here are lists of champs that I kept and champs that I dropped:

Looking at the dropped list, I think it has to do something with either not killing the enemy fast enough or dying too much. Now before you ask "Why don't you just stick with champions you are good at?", I hate whenever I get my champ banned then get counter picked. Although I am semi-decent at playing safe, I find myself relying on my team too much, which doesn't work when I suck or my teammates suck.
