Raging in a game will cost you the defeat.
Ok joke.Get some Tips (Ad most likely)
When u fight in the jungle,range is your partner.Use any weird spot to fight,so enemies cant come on you (for example,fight near baron and team fights on bushes?Go to the blue buff and hit from there,If enemy doesn't have a jump he won't touch you.)
Combining your auto attack with spells gives the illusion of damage.
Go ashe,use autoattack with slow,Volley and Autoattack.What it looks like on lvl 5?A 260 dmg burst.
What it is in reality?120 dmg +70+70.Seperately the dmg is not even noticeable.
Smartcast and not smartcast.On long cd spells,Try NOT TO USE smartcast (Ashe's arrow,grave's ultimate)
This will make you more focused on your shot.
Use smartcast in harass spells,since the position is what matters in harassing (Corki's q,when enemy steps ahead Shoot him,Without smartcast,you may lose time and the target)
Work your runes with your style.
Follow guides,see what they build,try it and then make your adjustments.
(Example:Most ad guides say FLAT mr on blues.I use mr @18.Its 12 more mr and in lane phase by 90% mr would be useless.)
