Beseiges are fun...
My only regret is that it gets sooo laggy... and occassionally you can't see the people who are helping you.... or the mobs that are killing you. As a WHM (white mage for those who don't know the abreviation), my skills are pretty near capped... but I'm an unusual WHM...

I think its rather fun... the only down side is the issue with lag. I need better players on my server though...

Oh... and skilling up in any weapon is good for beseiged... so long as its not doing zero damage...
