Dota 2 - How To Improve Your Gameplay

Map Awareness -

Mini Map

For map awareness, you want to look at heroes that are a threat to you. For an example, If your enemy team has a Winter Wyvern support in their safelane it probably not going to come to your lane and gank you, even if he does chances are he will not kill you. But if your enemy has a Spirit Breaker and you are playing Midlane with Shadow Fiend you need to be careful every time he goes missing from the lanes. It's really important to be aware of the timing. If you notice that enemy supports are missing around 5 min mark, they are probably taking their bounty rune and if they go missing a little more early then chances are they are stealing your bounty runes too.

If you notice enemy lane has double creep wave with 2 ranged, chances are they are pulling the creeps. You can guess how much time it takes for any hero to move from point X to point Y and assume their position. So if you can guess where they are and doing what, you can avoid getting ganked and know how deep you can push and when you need to get back or when you need to stay in the trees.
