First off, thank you for the post.

Late game, if played right, I will not disagree you are easier too kill. I use this build in ranked games and late game, you will get focused; you will get countered. But when their team needs 2-3 ults / full combos to take you down before you kill them all, your team has an easy time tearing through them. I don't play a game to have the best KDR, I play to help my team win, and when you draw fire from an entire team, while at the same tie being incredibly difficult to kill, your team will do better over all. I end games usually with most kill, variable deaths (depending on how well they focus) and highest assists. I am fine going into a fight and being focused so hard that the team kills me quickly, but when you play right, your team is right there, and you will die leaving the other team at low hp. A team fight where your team gets 1 death and 4-5 kills is a success.
Also, you are correct that against good players you don't 1v1 much. I said that that was a pro of this build, not the purpose. I rarely 1v1, but when I do I always win. I rarely 1v2, but I win most of those as well up until very end game. The point of this build, (for all of my builds in fact) is not simply to rape by yourself, but to make your team win the game.

I would agree that grabbing hourglass would be a smart idea if the game calls for it as long as it doesn't stop your ult. I personally don't use it, but that doesn't mean it doesn't work.

I have seen this build in RANKED matches. If played as described, you will rape hardcore and you will be very hard to kill. You simply have to know who to silence/fear. Additionally- yes you can be stunned and focused down, but if that happens the other team is already so low on health that your team will have an easy job cleaning up- unless you are stupid and try to 5v1.

+1 to the build and GUIDE. Use it like intended and it works.

Very effective build and great guide to go with! +1

This build is not very good, sure early game its nice and you are very hard to kill. late game is a different story. you have no defence and are easily countered. you drain is useless if u are stunned and u have such low hp and armor that u die instantly. Even if u get your drain off you die instantly. I improved it by getting an hourglass that way when u ult in you can survive for at least 2 seconds. good idea and concept but late game you are useless. I agree 1v1 you will never lose but when you play with good players you will almost never 1v1.
