With the release of Path of Fire expansion coming up, the Guild Wars 2 team has released a balance patch for the game. This includes but is not limited to; changing some stats of food and consumable buffs, gear stat updates, and most importantly, profession skills and trait updates. These updates are to bring in line the current skills to what will be released come Path of Fire and hopefully bring a balance between them. So this means that the skills that you are use to might now be the skills that they are now and that builds built before might not be viable in the way you built them to be. The list of changes are too long for me to try and cover here but for a comprehensive list please see the link below. Happy hunting.
