I simply felt as though it was rushed. This was a storyline originally planned to end in 7.0 and not 6.0, though for whatever reason it was scaled back significantly. We're not even getting a full patch cycle to wrap it all up, since 6.1 has been confirmed to revolve around a completely new story arc.

In other words, Zodiark, Hydaelyn, The Sound and Zenos were all dealt with in the same content drop. We've been here before, back in WoW when The Burning Crusade launched and decided to throw a bunch of well liked characters into the game world as raid bosses 'just because'. Subsequent expansions were then spent backtracking because the writers realised that it isn't actually a good idea to just burn through entire potential story arcs in a short period of time in a game that is built to last for years.

Some people might like it, some people don't like it. At the end of the day, though, clearly there's a decent amount of players - myself included - who don't think this was a satisfying way to resolve many plot threads that were built up for almost a decade.
