Keep Defense: N, The Hopeless act of defending an attacked keep with hopes of... A. Getting Annihilator Gear, B. Stealing Annihilator gear because you didn't get your Sov piece, and C. Getting some free renown.
However. Some people defend for other reasons.
Don't... Lose.. The keep...
Occasionally, you wipe as well... Wiping in a keep defense is nothing to fret about, it just means it's time for a game of Hide and seek with your favorite enemy. May I recommend in the bushes outside, or on the tallest tower, or if you're a Witch Elf or Witch Hunter, then just go invis and tickle Bright Wizards til they sneeze fire.
Remember, when they find you... Jump! It's Hide and Seek AND Tag :D
If there is no action in tier 4, you can always go down to the lower tiers and pick a fight there.
I've always wanted to see a whole WB of chickens :-D
A good thing, is when you're winning thekeep defense and everyone group hugs and then pushes out the door.
As you could see, the comment made by the sorc is very true.
