Should I start maining a champion before getting runes?
Hello, I am approaching lvl 20 (the rune buying lvl) and want to begin maining some assassins mid lane (mobility creep plus I like AD champs plus I like manaless champs which many of these are), but I am sort of wavering because I don't have runes. My fear is I will go into PvP without any runes, be put at a major disadvantage considering I already have to deal with a shorter AA range agaisnt some of my opponents, and quit the role.
Getting less specific, is it a good idea to begin maining a champion or champions before you own rune pages fro them, in order to be good at them when you do, or is it better to buy some "general runes", then costimize them later for the champion you decide to play?
