The Basics Again and Again
Ok let me say this one more time for everyone: The most important item is....
Scroll of Teleportation
This is what separates the good players from the bad ones. You always want to have these, so you can tele in for ganks or help guard a flag. I'm surprised how people with over 300 games, still dont get this! If you see the signal go down, you tele there the next chance you get! Or at least fake it!
Nobody expects this in early game, but starting in midgame you just don't leave the shop without tele scrolls. You simply dont!
Thanks for listening.
