this is a little trick my buddy taught me;
when playing annie it is awesome mindgames to be a frail looking little girl with 4x on pyromania, when they try and gank you pop moltenshield as the 5th spell then say HI with Tibbers!
dont walk around with a magic blue belt of wind...

Annie:
Before you recall and you need to advance your passive use her fire cone, then recall then fire cone again. +2 easy.

General:
You can teleport to tibbers, mushrooms, or humdinger's turrets.

Singed:
If playing a tank, max poison and goop (obviously got lvl 1 sling). The goop is deadly at max. It can be used behind an enemy to deter an escape route (like anivia).

Annie can build up her stun charges using 2nd skill being at the base from the very beginning. Then when you go in lane (TP better cause you wasted time charging stun) - you will have AOE stun with dmg. Throw in one teammate and exhaust and FB is inevitable

An early game tactics also can include: killing dragon (you need 5 ppl for it), going as 3 or 4 into bushes for 100% FB (possibly with double kill), this can be done after killing dragon; killing golem or lizard together (f.e to get lizard buff for your Teemo).

When playing as rammus and when your enemies are attacking your tower, walk right up next to them and taunt. When you do this, there is a higher chance they will hit you, getting tower aggro. After the first hit, immediately run backwards, do a 180 and smack them in the face with a powerball. Guaruntees a kill early game if the enemy does not have flash (heal doesn't even save them heheh)

As Katarina, you are able to Shunpo towards enemies, OR teammates. If you see yourself getting dropped and a teammate ahead of you do your best to shunpo to him or shunpo to a minion, or neutral minion a very overlooked skill which gives Katarina a much higher survivability.

When teleporting to a minion, the minion becomes invulnerable and passive until you appear. This can help when defending a turret. You know those times when you see the enemy and his minions getting to your base, that has very little HP, killing the very last of your defending minions? If you teleport to one of those minions, the enemy minions won't be able to advance until you appear because they are held up attacking your last minion, giving you a defensive edge thanks to minions and minions.

As Sivir:
When an ally is being chased by some enemies and you cannot do anything to stop them(obviously, you are Sivir no stun whatsoever), stand in a safe distance/place, hover your mouse above your ulti, and check if you ally is inside your Ulti range(it's huge!) and click R. Watch as your ally outrun them, and feel warm about yourself after reading Tnx and GJ on the chatlog.
