All classes can have a 100% winrate against the current AI’s. Maybe if/when the AI gets better we will see a more complex battle arena meta.
It is not that rogues are weak but “natural” rogue progression leads to bad PVP builds. Rogues get bonuses when investing into Power (the weakest and least efficient stat). The bonus is a very low dodge chance which is completely countered by the Flawless Victory trophy. To make a good PVP Rogue build, you will need to make it very different than the natural progression of the class. Don’t make “glasscannon chars”. This patch brought in higher HP and MP potential so Warriors and Wiz “naturally” win as they invest into HP and MP naturally.
@Msiiek:
Thank you for reminding this thread that by putting the same/similar affixes of a build onto another class, it will function nearly identical especially if you use Battle Mage.
