Sorry for quoting back a day but I couldn't let this slide.
Lets not re-write game history so quickly. They were correct. 8 People beat T5 before it was nerfed. T5 wasn't cleared for a long time and people were insisting some of the mechanics were simply broken. The devs left the content at the very hard setting untill BluGarter cleared it the first time. After they cleared it a patch was released along-side a post from YoshiP where they made it easier.
