I started when it was released in US, but switched over to EU when it was released here as well, you just need to play a lot of normal games and you will eventually learn everything and make it a habbit ^^
When playing Kayle you rush rageblade then get boots, tooth, gunblade, deathcap and bloodthirst. ^^ Your ultimate gives you 2.5sec immunity to damage (not CC) so you can kill ANYONE in the game. ^^ I remember being fed early and ended up with 52-0-7 as Kayle, she can be really amazing, but her ratio sucks hard. Recko does 100 damage on lvl 1 with 60+ ability power, then you have to reduce from MR, so less then 100 :/
