This is the honest truth of this game. Short and sweet.
PvE is loaded with constant new content every 4 to 6 months.
PvP is an unbalanced mess that is favorited by those who exploit known broken sets in the game and run in elitist groups to reap the full benefit of the exploit.
In addition lag is crazy. It'll always win. You can't escape lag in pvp (Cyrodiil in particular)
Everyso often the game will do a patch to "nerf" sets like these but not enough to discourage their use and promote diversity.
Over all the game is fun, creative, lively, aesthetic, highly customizable and honestly a good way to be social and have a gamers moment of peace. A 3.8 - 4/5 rating for me.
PvP just might make you not like the game. Over competitive and laggy.
