I was never big on MOBAs before League, and thus I was reluctant to give it a try. Actually, the first time I played it, I had a HORRIBLE experience. I used to play World of Warcraft quite avidly, and was a multi-time Gladiator in Arenas. Since I was very good at and somewhat obsessed with WoW, I had trouble getting into other games and learning how to play them simply because I didn't want to bother. I was also a bit of a toxic player, actually I was quite a jerk to friends and random players in the game. Anyways, my original League of Legends story:
The first time I played League was in 2011. The game was really popular, and I had a lot of friends who played it. One day, on my usual Ventrilo server, my friends asked me to install the game and play it with them. I was reluctant (as I stated above), but I decided to give it a shot. I had played the original DoTA once or twice, and was never really that interested or good at it. So, my MOBA experience was definitely "beginner" level. So, I get the game installed and make an account and am ready to go. Naturally, you'd go into tutorials or bot games first, right? Nope, not me. My friends just invited me, a level 1, into a game full of level 30s with runes and masteries. They just kept saying "oh, you'll get it quickly, you're so good at WoW!" completely ignoring the fact that this is a COMPLETELY different game.
So, we're in champ select, and I ask them who I should play. They all made their picks, the only one I remember was Annie mid by one of my friends. They told me to play Katarina. So, I decided to just do what they said and picked Kat. Again, I had no idea of how the game worked or anything. So we get in the game, and I ask them what to buy. No one said anything. They just ignored me and went to their lanes (which at the time I didn't understand at all). So I just bought what was recommended (IDK, probably Boots + health pots or maybe Doran's Shield) by the game.
I was constantly asking "what do I do?" to my friends, who just kept overlooking me and playing the game. I was pretty angry, mainly because I was a top-level WoW player but I was like a fish out of water in this game. I basically jungled without killing camps (I just ran around and tried to gank the whole time) because I didn't know what the heck was going on.
I finished the game with 1 kill (better than none, right?), 20 something deaths and who knows how many assists. My friends then laughed at me because I fed. So, I got angry and didn't touch the game again for about 2 years. I started playing again in 2013 and eventually passed my friends I originally played with in ELO (they capped out at high Silver and I made it to Gold 1 with Plat 3-ish MMR on NA).
My main account is now on LAN due to me living on the east coast and getting a horrible connection to the NA server, but anyways that's my League of Legends story. The reason I started playing again was because a friend of mine begged me to and gave me the hookup with a starter pack that included a bunch of cheap champions and a couple skins. I also abandoned my toxic demeanor (mainly cause I grew out of it) but am now just a casual gamer. However, I love League of Legends (in the words of Imaqtpie and KiWiKid)!
I actually played against Scarra and Nientonsoh in WoW arenas back when they played. Seeing these guys had moved to League was part of what actually made me want to give it another chance. Granted, I've made nowhere near the accomplishments they've made, I just really love the game.
TL;DR: My first game was a feed-fest, my friends did not give me any reason to continue playing but eventually I did and now love the game.
