First of all, i want to clearly point out that I fully respect Anet and their work on this game that they have delivered to us, its really a great game. However, we can probobly all agree that this game badly lacks some of the game aspects which I am going to point out below (Yes I know these things have been pointed out thousands of times, I just want to express my own opinion and some additional interesting things). Also i want to say that English is not my native language so pardon me for my grammar mistakes.
Now to the main points of what this game really needs to become the best mmorpg on the market
1. Guild vs Guild mode
Im just repeating what has been asked for and talked about thousand times, but this is absolutely true and very needed. I believe this would spark a little bit more endgame and it would definetly improve the game quality by a lot. The ability to see the guild rank would be nice too, like a guild vs guild ladder system or something like that.
2. Guild Halls and real Player Housing system
Purchasable Guild Hall which would include diffrent styles, sizes and structures of Guild Halls for a diffrent amount of guild influence and gold perhaps? Also the ability to upgrade Guild Halls (add workshops, bank system, decorations and other interesting stuff). The current “home instance” system at the moment atleast for me feels really dull and uninteresting. I know that Anet is trying to push out this current system as a Player Housing system really hard, but at the moment it just doesn’t cut it really and doesn’t feel like home at all. Real Player Housing should be a one structure rather than an area or a district to feel like home. The House should be upgradeable for gold (furnitures, workshops, bank system, decorations)
3. New PvP game modes
I believe this would absolutely revive the PvP community by a lot. Give us modes like “Capture the flag” , “King of the Hill” etc. Anything like this would instantly improve the PvP quality. The current one game mode for 2 years really drained out all of the life from the PvP community. It needs resurrection.
4. Expand the world
Theres so much potential here. Far Shiverpeaks, Bloodlegion Homelands, Crystal Desert, Desolation, Vabbi, Elona you name it. So many areas for so much more content and a more epic world overall.
5. Introduce new playable race and class
I would actualy say at the moment further class balance (not that its too much imbalanced, but still needs some work) is more important, but seeing only 1 new race and only 1 new class (preferably a 3rd heavy class, to even out 3-3-3) added to the game would be more than enough and very pleasant. Perhaps this could be added along with map expanding in a new zone? Would make sense.
6. Add more endgame
In all honesty I really feel like the game lacks some more endgame (I know that some people will disagree with me here and will say that Living Story is our endgame, but story continuation is no endgame really, its just story, thats it). Of course the endgame could expand if the above points were introduced to the game, but still, without those i feel like it needs something more. Few examples: a single new dungeon, new legendaries to work on, legendary armor, new traits and build variety, going for minmaxing stats (instead of only +5 power,precision,toughness and so on, why not introduce +6 +7 +8 +9 like we have with agony? It wouldnt be game breaking, but at the same time this very small addition would have a bigger impact for players who want to invest into gear and grind for maximum stats). These are just few examples for extending endgame.
