-tips... Unfolding Icefrog's Gameplay Suggestions

In my opinion, "-tips" is a great idea from Icefrog that not only helps the beginners but also clears to many of us the actual role of a hero in the game. For those who don't know what "-tips" is, just use this command when starting a game and a bunch of advices from icefrog will come up during the game regularly.

And for those who love the "tips" from icefrog but don't have the patience to wait the whole game for them to show up, here's the complete list of tips provided by the -tips command.

Note: There are no tips for Tauren Chieftain, Batrider or Goblin Techies.
