HOTS was quite different from the original (vanilla) GW2 with the way zones are laid out (verticality) and the aggressiveness and density of mobs, etc. It could be quite fun if there are a lot of people online, but frustrating otherwise.
I wonder if HOTS helped or hurt GW2 overall and where Anet might take the game in the next expansion.
What direction will they take with the next expansion? Any guesses based on their most recent updates?
