Ah, Anniebot... Yeah, she's definitely a killer. She's kind of like how Ryzebot used to be. Before his recent changeup Ryze bot would walk up to you and just spam every spell he has at you. And considering how Ryze has incredibly high ratios, he did a LOT OF DAMAGE. But now spell flux does less damage so Ryzebot hurts less and Anniebot makes people QQ cry moar.
EDIT: The reason Anniebot makes people rage is because her AI pattern is very simple. Wait until she has 4 points on her passive(every fifth spell stuns the target/targets), walk up, use your E(which is a shield that boosts her defensive stats), drop a bear(her Ult is 'Summon: Tibbers' and calls forth a pet and also does some heavy nuke damage.) Drop your W on the stunned enemies(this is a nuke that stretches out from annie in a cone, blasting everyone within the range) and then hit hte lowest one with her Q, and back off until she can slam more damage on the enemies.
This is dangerous because THAT IS EXACTLY WHAT ANY GOOD PLAYER USING ANNIE WOULD DO. ...And the bot isn't slowed down by having to click a button or anything.
EDIT2 point o:
A bit of clarification. Every character has 5 abilities. One is a passive unique to the champ. This can range from anything like annie's to Kog'maw's(Kog'maw's passive - Icathian Surprise - has him increase his movespeed and explode on enemies for True Damage(not reducable by stats) everytime he dies. So if you kill an enemy Kog at level 18, just hope you have more than 450 hp!) or Cho'gath's. Cho'gath's passive heals him for flat HP and MP everytime he kills a minion. It's not a whole heck of a lot, and far more useful in the laning phase than lategame. But Lategame he's just a meatshield so it SHOULDN'T MATTER.
Anyway other than the passive, you have three standard ability. In any one game your max level can reach 18. Every level(including level 1) you can level up a spell. Spells can be leveled up to five times, and then you have your Ult. Which can be leveled three times, once at level 6, again at level 11, and then again at level 16. (so basically after every five levels) They're typically your most powerful ability. Typically a player will want to level one ability to level 5 as soon as possible(which is level 9, since you can't ALWAYS level a certain ability. I'm not sure exactly, but at level 1 you can choose an ability, level 2 you have to pick something else, at level 4 no one ability can bypass level 2, you'll ALWAYS want to get your ult at level 6, and then at level 8 you can't have higher than level 4. So, level 9 will see you max out your first ability.
Note: I'm willing to help anyone from CP get acclimated to the game ^^
EDIT THE THIRD: Oh lawl I keep editting this post.
I just read the Refer A Friend page. One of the rewards - the highest tier - is getting an all expenses paid trip to Riot HQ to build a champion with the Riot Team. The number of people you need to refer to obtain this reward? 10,000. Yes, you have to refer TEN THOUSAND PEOPLE to League of LEgends(and they have to reach summoner level 5) in order to get this done. But it would be so amazing anyway.
EDIT 4: Meant to add this at the end of EDIT THE THIRD but forgot.
This is MY refer a friend link:
http://signup.leagueoflegends.com/?ref=4d91123296f94643249693I added to the first post, as well as added a 'summoner name' section. Just name your summoner name here in the thread and I'll add you to the list.
