For those people who think HoT is not good enough, afraid to buy it, or think its not worth the money. The second expansion is already being made as we speak. This was mentioned in the last Community Showcase Live featuring Gaile Gray.
HoT was not a huge expansion in the idea of area like most are in other games. Things kinda got messed up here and there. Desert borderlands was kind of a flop when it came out. The grind was not liked at all due to the mastery system and Specializations. Yes Anet tried new things and they flopped, but that’s how you learn.
Then the spring update came out it did not fix everything, but did help a lot. All the raid wings were finished, and now includes a bit of training using golems. Anet has to think of three separate areas of play. First is SPvP which they want to have an Esport design in it that is their baby which is Ok. They have always put SPvP above everything in their games just get used to it. Second is WvW not quite SPvP but not quite PVE either its a combination of both. Last is PVE which this game has a lot of area to cover. PVE you actually have to level to 80 in the zones, because the game will not level you instantly like SPvP or WvW will .
So when they make an expansion it just isn’t about one part its about all three. Again mistakes can be made, bugs can pop up, and content can be disliked. That does not mean Anet isn’t trying to make the best game they can for us, because they are. They are trying to make a game that’s not like WoW or EQ2 in the standards of games. Anet is trying to be different but still familiar at the same time.
The HoT expansion was a set up for the future expansions, because unlike those other games the core game and expansions will still be relevant to the entire system, dailies see to that. Also unlike other games where you have a new expansion and every thing goes gray in the old areas you used to play in cause your just too strong for them. Only newer people play in those and grind to get to your level and leave those puny areas behind. Some do have mentoring systems in them though.
Guild wars 2 vanilla is kinda funny if you think about it. Vanilla in games means nothing was added to the game at all when it started if I understand it correctly. Almost immediately they added new content of course for free at the time. Southsun Cove. then Living world, then Living world season 2 with Dry Top, and Silverwastes. They also set up the new specialization design for HoT. Actually an expansion worth of content for free. Now how can that still be vanilla?
So should you buy HoT to stay relevant? Yes because of the gliding (ok ok the gliding is not what its all about, but it is fun) The thing is Hot is not going away and its the beginning of the future expansion design in the game. Which like Guildwars campaigns will link the game together and it will all be relevant. You can wait until the next expansion if you would like which will include HoT in it, but you will have to catch up anyway, cause they are not gonna just give you everything it has to be earned. It will save you some money though since Anet wants GW2 to include it all for one price as the game grows.
