So i decided to participate in this contest, and i will start with telling you why i play LoL.
This game has been recommended via another MMO game for me. Even though i didnt like the graphics first,i kept playing, because i knew that i cant judge a game on a mere first impression. I really liked the idea of fighting with heroes. It was the same feeling as when we were watching a typical fight based cartoon back then, when we were kids. (Son goku etc.) Where you have certain abilities and artifacts, and you have to think, and try to counter an enemies abilities. An extremely addictive type of gameplay. Even though there is only one really played map(Summoners Rift), people tend play thousands of games on the same map,with same graphics for a good reason. The skillful fighting itself whats interesting.
Now about my favorite champion in LoL.
Personally i really enjoy playing mages, especially, the spell-vampish type. For instance i really liked to play Vladimir, and still enjoy playing him, tough my personal favorite right now is Jericho Swain. His abilities are all so intresting. Damage amplification, slow, and a very hard to place, but rewarding snare. Mainly dots, not nukes, still very powerful mage. His ultimate is also one of the best's. He can be built in many ways, though i find the tankish mage to be one of the bests, undying in a teamfight, while focused, and still deal crazy damage. (Even though ignite can severely cripple you, with a golem buff, i remember surviving many fiht even ignited, and focused.) I also like how clever you must be when laning, so you never starve mana or run out of health. Requires good micromanagement, but totally worth it.
Apart from his skills, i find him a very stilish character also. One can understand it if played him, and knows his sayings, emotes, or reads the Journal of Justice (very interesting stories of swain and the Black Rose, noxus). Myterious, stylish,harsh personality, hilarious ultimate with bilgewater skin and so on.
