Fight Maneuvre

Items & equips selection and last hit & lane control skill may be easy. But even masters can make mistakes when it comes to fight maneuvre. Now here's my opinions, just for reference.

1. Always carry a Town Portal Scroll!

Town Portal Scroll's is by far the best and most basic item in the game, just before Boots of Speed.

Always carry a TP SCROLL!

Why?    1. Allows you to assist a lane and potentially turn a gank on your allies into a counter gank, saving your allies and grabbing a potential kill or two.    2. Your able to escape a oncoming gank!    3. Your able to escape a gank!    4. Carrying TP scroll allows you to farm lanes constantly.    5. Your able to push a lane, grab a tower when the majority of the enemy team are mid*

When to do this?->1) When you are unable to defend regardless of your presence. (Take note, carries.)->2) Able to push hard enough to force a teleport back from one of the enemies, gaining a slight uphand if your team was to teamfight now.  

2.Pushing - Advancing to enemy towers

A push is a very important part of the Dota2 game. In pub games(public player games) it is almost always very hard to organize your team to do a push. Most people want to go into the jungle and farm neutral creeps the entire game until they have full items. This is not how you play Dota2 well.

Generally, when your heroes are powerful enough to do so, you want to organize into a 5 man pushing team, and you want to destroy enemy towers. This gives you map control, and this gives your team 1000-1300 gold. If you destroy 3 enemy towers and they have 0 of your towers, your team has a 3000-3900 gold advantage. This is a huge advantage.I advantage when fighting by your team's tower(damage, see invis, etc.) so defending a tower is almost always beneficial.
