a normal player will not use authority to do this dungeon (i mean it is not a commun build especially on pvp server), in all previoUs version of the game thralls were able to survive if no major error in this dungeon.

thralls were not worthless for base defense pvp when 12-18k they were giving lot of time for a defender.

and i know there is golem now, and their intend was probably to fullfill this lost function, but golem are buggy, they do not have range attack, and are very weak to a certain type of weapons, so for me they not fullfill role thralls were able to do and that was giving you something like 1h to 2h if lot of them.
