im kind of experienced with this build now. and all i can tell, after 10 earlygame frags and like 2 deaths, when it comes to lategame/teamfights, im autodogmeat after throwing out 221341234 crits. and because of the fact that pretty much everyones running after my attacks, i wanna revive lol

Twitch is definitely not meant to be played as a hybrid. There are a lot things wrong with this build and I don't want to go into detail, but two big mistakes on him are greed instead of the 15% magic penetration as well as a Guardian Angel on twitch. They know he'll revive and since he's a squash, the moment he revives, he's pretty much dead again...

I may not be a pro, but i know how to use twitch and always adjust according to the game, but your build is more on survivability instead of major damage output.
