I've been playing League of Legends on-and-mostly-off since 2010. I'm on again, flip-flopping between the PC client and League of Legends: Wild Rift (the faster-paced mobile version that has most, but not all, of PC League's champions).
Because I've been away from OG League for so long, I'm only at level 21, so I have a long way to go before I can start playing ranked. In Wild Rift, on the other hand, I've performed consistently well enough to reach Platinum rank by the end of last year (it reset to low Gold at the start of 2025).
Going strictly by in-game stats, my three favored champions in League are Sivir, Xin Zhao, and Lux, but I have to challenge that assertion since I've only won so far with Siv, Annie, and recently Diana. In Wild Rift, it's Seraphine, Morgana, and Milio (all of whom are Support champions, as opposed to the ones I've played recently in League on PC, who are typical picked in the middle and bottom lanes). I've yet to "settle" on a specific selection of characters yet, since the "pick/ban" system used for more serious games requires you to be skilled with multiple champions. Maybe after a few more months of play I'll know my strengths and weaknesses. I'm not gonna tell you what those are, though!
