I just need one champion.

So I have 2 champions, one is gnar which is my main, and second is nunu which Isn't my type of champion. As you can tell I don't have much of a variety at all and yes I could do the weekly champs but if I get into one then the next tuesday ill have to change. Anyway after playing alot of gnar hes gettin kind of boring only because I play him so much, So I found kindred on a weekly free champ thing, aka this week and had tons of fun, if anyone has alot of Ip they don't know what to use it for and there feeling kind then please help, and if you rly want downvote and say im stupid get ip yourself then do it I dont care im just asking to learn and get a champ and have fun
