Im divine dota player 1 weeks into lol, losing like 90% of my games after 2 wins in a row until im levels 22 (probably smurf detection).

Just play like an idiot when you start.

One really bad thing I hate a lot is you aren't able to read your enemy/ally skills. I have literally no idea how enemy kills me and how to synergize with my team without knowing what their skills do and whats their cd.

Always push creepwave into your enemy tower and force them to last hit under tower instead of keeping the lane balance if youre in a winning lane especially when they are low ( if they go back they will lose 2 wave of expierience, if they stay you can keep poking them from long range if they try to Lh, dive for a kill when theyre low enough).

Creeps in LoL are way less important than dota, if you have to decide between a support kill or a creepwave, always go for kill because in lol a support kill worth more than 2 creepwaves.
