Loyal Defender

This achievement brings back alot of good memories :-)

The way I worked on this was to get five or so people in the keep and wait for an alliance player or two to poke their head in and aggro the general, prefferably before they are actually working on killing him. Most of the time they'll attempt to run back out. That's when you use whatever slows/stuns/roots you have on anyone inside the door, and watch them get mowed down.

It's not 100% guarantee you'll get credit (due to you needing to assist in killing the person), but it worked for me and was relatively painless. It's especially effective if you have a number of people there so you get damage on the target plus more stuns and slows. A comment above said you need 50% of the damage, but it seemed to me that it's a lot lower, but it's hard to tell for sure when they die so fast.

**EDIT**
Another thing that I didn't even think of before...if you have a DK to Death Grip people into the room that will up your odds quite a bit more. Plus it's a lot of fun to watch.

Who delivers the killing blow is irrelevent. You just need to do more than 50% of the damage dealt to the enemy player. If an NPC does over 50%, you will not get credit for the kill.
