Alright guys im getting pretty tired of seeing people pay for waypoints that can be easily obtainable. Its just pissing me off the real exploit is the people who charge for that crap. Anyways im going to make this short. Even if its known or in elite I really don't care.
Step 1: Choose the act and quest that you want to go to in a lower level.
-Example: Act 4 - Prime Evil Normal
Step 2: Start your new game and once it loads log out immediately.
Step 3: Click on "Public Games" and Oh hey look I can do inferno Prime Evil ain't that some shit. Join the game and leave.
Step 4: Resume your game like you would with any and you have the WP.
Note: You might not get the specific WP that you're looking for but most of the time you'll get to where you want to be.
That wasnt hard at all. So stop wasting gold and make it so you don't have to wait on other people. That simple.
