Carries in DotA

I think many people have an impression that carrying in DotA is just afkfarming for 40 minutes, then coming out with 神装 and soloing the entire enemy team.

While this may or may not work out depending on enemies, teammates and lineup, I believe that carries should have a more active role in the team than simply afkfarming.

Firstly it makes the game less boring. Face it, afkfarming is BORING.
Secondly, the time most carries take to develop is way too long. Terrorblade afkfarm will end up giving you a late game powerhouse, but that makes you totally useless during the 40 minutes while you're afkfarming, which may well make your team lose.
Thirdly, the time and effort spent on helping your team out will often pay off for your team as a whole. For example, carries running Helm of the Dominator for lifesteal can easily dominate multiple Centaur Warchiefs and use their stomp in team fights and ganks while farming neutrals or another lane.
Finally, neutral camping is inefficient. Turtling in the jungle killing neutrals may be a safe and secure way to farm up to your long-awaited 神装 which many carries really need (such as Troll, Terrorblade and Faceless Void), neutral camping offers no pressure to the opponent who may gank, farm and push at their leisure. While lane camping is dangerous, it puts pressure on towers and ganks are easily avoidable by map awareness and warding.

While this does make carrying much more difficult micro-wise, but a carry-ganking hybrid could potentially be much more powerful and beneficial to your team.
As a result, I have been promoting less farm oriented carries, especially those with ganking potential, such as Drow and FV. So far has been rather successful, but need more experiments to see the full potential of these hybrid builds =)
