It's so fun, I get to play against people who are all over the place on their mains, I've faced players of all skill levels every day, been dumpstered by a GM LeBlanc, and wiped the floor with a gold lux, made lots of friends, it's really fun once you get past the new player part and the system realized you are smurf xd
Don't even care that 90% of the time I get my ass handed to me, I feel like I'm learning so much, seen some amazing Kat players, Akali, Yasuo, etc. It's nutty. I very rarely get to experience things like this on my main.
10/10 would recommend making a new account if you aren't opposed to having a couple 1 sided games for the first few levels.
