Yep, I'm retarded and I'm one of the worst DTs in the game and I only need the cloak to be full t4. This is a videogame, It's designed to have fun and kill the mobs easily. People who keep talking about "the best players" and "teaching to play" and "the correct way to use a class" and all this bull.**** only steal the fun. Even the "worst" players clean T4 at the end so take it easy, have fun and cut the elitist crap.
PD: I've met plenty of "gurus" and their lessons most of the time are conflicting each other.
