The expansion that changed Everquest forever, and not in a good way.
The zones, while large and fairly well designed in structure, where very difficult to travel in. Random see invisable mobs and long runs made having a class that could invis with you a must, slowing group creation and forming.
The mob difficuly was high, with well rounded resists being a must. The expansion ended up catering to only the most well geared and to classes that could kite kills so that they could avoid a large portion of the procced spells.
It was also a major deviation from the original Everquest theme, with alien like NPC models and an unclear storyline. The high fantasy feeling almost dissapeared as we fought mobs fro another dimension that did more damage to lower geared players with spell procs than melee damage.
Progression was partly group based and partly raid based. In the end it offered little to the casual player until the level cap was raised the following expansion.
This is a good buy for the hard core raider, if only to keep with the guild and get the new AA points. Otherwise this was one of the most frustrating and broken content filled expasions to date.
