EDIT: HOTFIXED
Yes, as the title states this is the best exploit in a while, why? Because it's a REAL exploit, no bullshit tips, a real bug which can be taken to YOUR advantage.
First off all, this requires you to be a warlock or have a warlock in your party whohas the spell "Demonic Circle".
Join up for WSG and head towards the enemy Flagroom. Once there, let the Warlock use the Demonic Circle somewhere close to the Flag (Close enough to teleport from the Flag to the circle), now let the Warlock grab the Flag and let him teleport straight after (Has to be very fast).
What you'll see is a Warlock holding the Flag, BUT the Flag is still at the spawnpoint and is still pickup-able. Let a second person grab the Flag and head towards your base.
Let 1 of you score first (Not at the same time!!), the other flagholder will drop the flag after you scored, but after the flagdebuff faded (3seconds) he can pick it up again and score again!
To make it short, with a Warlock you can dupe flags and therefor you can score multiple times in one run (easy achievement).
Explanation:
The Flag despawn does not register you took the flag, since you Teleported straight after, therefor you can pick it up again.
This can be extended, the Warlock could pick up the flag -> tele, drop it and let it be taken by someone else, then the Warlock takes up another Flag -> Tele, drop it and let it be taken by someone else. Rinse and Repeat
ENJOY .... while it lasts.
