LoL, No I'm Not Laughing

So I got into a game that's pretty popular and sure you've all heard of before called League of Legends. I'm a super-noober at the game but I've gotten better. At first I sucked so hard that playing Beginner I'd die all the time and my team would manage to lose, but now I do okay on Beginner. I mostly play Intermediate Dominion, yes I prefer to play against A.I.s. I'm going to try a P.V.P one after I finish this post though. I tried out a couple of champions and at the moment my favorite to use is Udyr. The only reason I'm using him is because he's one of the free champions. Last week the champion I always used was Mordekaiser but I had trouble figuring him out. I didn't realize until Saturday that his abilities used up health which is why I was dying so often. Now here's a really nooby thing, I didn't know that abilities didn't affect structures. I'd be taking down a turret and using abilities on it thinking it was doing something and ended up dying faster. I do own one champion, Annie. I don't know why I bought her, I guess because I liked her Ult, but I sorely regret it. Right now I'm going to work on getting promo codes to get Riot Points so I can buy Udyr. I've figured out a good strategy too. When playing Dominion I cycle points going Bear Stance, Tiger Stance, and Phoenix Stance. After finishing all three I add the rest into Turtle Stance. That's just because Turtle Stance isn't as useful as I'd thought it to be in Dominion because the health and mana steal is weakened. I never really figured out Turtle to begin with though because I'd stay in it when I needed health, then read a strategy guide and it said only stay in it while you have armor from it. But, my strategy is use Bear Stance, which increases movement speed, to get to the Capture Points then when fighting a champion I cycle between Phoenix and Tiger Stance because of the activation effects. That's also my general combat strategy when using Udyr. Because I don't play Classic I have no real strategy but if I had to make one I'd be in Turtle Stance when there's only minions and use my combat strategy when a champion comes by. Then use Bear Stance over and over if I need to chase the champion. And when taking a turret I use Tiger Stance because it increases my attack speed. As far as equipment goes I buy the Trinity Force first, getting Sheen then the Zeal. After that I go for Randuin's Omen buying the Giant's Belt first. After I get Ninja Tabis. Then Wit's End. It's a pretty good strategy for buying. Some other champions I want to get are Malzahar and the champion with the giant boomerang shuriken. Sorry forgot a lot of the names. And of course Master Yi, from the way my brother talked about him he's really useful if you just spam Meditate.
