I think it's funny that once all the features of Legion were revealed, most of those Nostalrius vindicators shut up. Legion is going in the right direction. Blizzard has a good chance to revive WoW and fill the servers up again.
so i want to hear from actual people, does this expansion make the game decent again
Blizz is making an effort to revive dead content, so there's something. Some of the new quests can send you back to deserted zones.
PvP is entirely skill-oriented now. Stats in PvP are normalized so a player with good gear doesn't have a decisive advantage over lower-geared players. Instead, they put focus on a Honor-levelling system. Pvp has it's own skill tree now and it's pretty neat.
Artifact weapons are also a step in the right direction since they have their own talent tree-esque system as well. Leveling those up will be an important part of character progression.
