End of the year: What to expect?
This is still the most current info we have on that (I think)
https://www.guildwars2.com/en/news/looking-ahead-guild-wars-2-in-2013/
Things we haven’t seen yet, but should by the end of the year:
New Skill and Traits
Crafting Taken to 500! “will be used to craft ascended weapons, armor, and more.”
Legendary Gear and Precursors: Including “specific way to build precursor items” and “new legendary weapons and new types of legendary gear”
Intro things: "To prepare the game for its eastern release, we’re building a new comprehensive “level zero” optional tutorial that teaches the core basics of the game. We’re also adding new story steps at levels 5 and 10 to help better teach core mechanics as players grow. "
Edit: Unless you meant about the LS, in which case I have no clue, other than a Slyvari will be involved next month. Along with the return of Halloween and Wintersday.
