I noticed since the expansion released that there’s a section in the achievments that reward players who have legendary weapon.
I have Twilight since about 2 years and I know a lot of people that have legendary weapons and, like me, got them the long way (not by putting $$$ in the game to swap for gold and buy it).
I think, and I don’t think I’m the only one, that players that got legendary weapons BEFORE the expansion should be rewarded.
