The
Badge of the Trial that are awarded in siege are used to get the guild titles. The guild titles have the attribute bonuses and some special skills, ie
Fire Training. The max badges per a siege are 15, which requires first in all three catagories(defense, offense, logistics) and to win the siege. To get all the titles, it would requires just over a year of winning every siege
AND placing first in order to get the 15 badges per.
I do not defend shadow guilding as its unfair to lower lvl/gear guilds and people that actually want to play the game. I just look at siege that even when I lose, I still get three badges, some guild resources to contribute, and some junk gear to sell for gold.
