Hello, I am tired of being a leecher, but I do not know of any scams or exploits in WoW that are not already on this site. I do, however, have a little trick I came up with in Gears of War 2 on the Jacinto map involving the mortar =)
Dunno if it can get me rep, but either way, here it is:
The trick is most useful in guardian or in situations where the last man is cooped up in the nade tower.
Get the mortar and take it upstairs. Head towards the tower the enemy is, and go down the steps that lead to boomshot/hammer of dawn. At the bottom of the steps, look up at the tower. You will notice that the tower window has a protruding archway, at which point you may already be able to conclude where I'm going with this.
Get about 3-4 yards from the tower window and face it, then launch a fully charged mortar shot at the tower. If done correctly, the shot should bounce off the top of the archway and into the grenade tower, killing all the dirty nade campers within.
Once again, this works like a charm on guardian, since nine times out of ten the leader is camping in the tower.
If you have any questions or would like a demonstration you can PM me or contact me on xbox live. My gamertag is aRealClassAct.
Enjoy!
EDIT: Just noticed I'm not even a leecher! lmao *fist pump*
