Wooden Potatoes have a really interesting video regarding biggest problems in GW2, which has some interesting points. I wanted to open a discussion on the forums regarding some of these points. Good way to open dialogue and provide feedback to devs.
To summarize points by WP:
I would recommend watching the video.
I will focus mostly on PvE, as the video did. It also is the back bone of the game.
One of the main things I liked about GW2 is the gearing system. Relatively easy to get into. And ever lasting. I detest games with increased leveling systems and ever changing gear and power creep. This is an advantage that GW2. Unfortunately, this is where also Anet kinda been falling behind lately, and in my opinion, is the major issue the game has been facing in last few years; lack of diversity.
Devs added mastaries to create a horizontal progression, with HoT. Conceptually, I think this is a great idea. Gliding is surely one of the best features introduced to the game. The remaining HoT mastaries have the issue of being too localized. An issue that the devs made again with Ice Brood. Dunno why, since it was a heavily criticized area. At least in HoT the mastaries were purposeful. To me, they feel more like when a LW episode is released, someone at Anet checked a box that there is a new mastery, even though it has no game play value.
Additionally, we could use more gear options. There is no condi dps gear with concentration. How about a new stat or two. We could have a gear that speed up actions, similar to alacrity in SWTOR if anyone played that game, less the CD reduction, which could be another possibility. These could alter the game play experience in various ways. Or any other stats ideas to change the game play around and add more options.
I understand why there is no new elites, but why are there no attempts to add options in open world PvE? How about opening elites weapons to core (open world PvE only), or cross class, since the weapons, skills and animations already exist (again, open world only). Balanced or not? Who cares, if it is locked to open world PvE.
Difficulty is a complicated topic, especially for someone with my in game experience. I run circles around most players in sPvP. The poor NPCs do not stand a chance. The issue though, GW2 plays more like an action RPG, and requires fast reflexes. I think best design is to make content hard and yet accessible. This never worked well for GW2. Content is relatively easy. When devs try to make it hard, they tend to do it very poorly. I think devs tried to make the new map somewhat harder. Will see how this pans out.
I kinda covered gem store. Lack of co-operative play, not sure what the issue specifcally is, GW2 never felt like a social game for me, like other MMOs.
PvP.... so many issues. Quick run in sPvP issue (IMO):
I do not WvW.
I want to add one more factor here, fatigue. I think this hits LW the most. See, the content may wear a different skin, but for the most part, I have seen it before. This has been my impression of LWS4 and 5 so far. I played this before. This is an issue all old games have to deal with. Anet is doing close to nothing on this front. How is Bjora Marches different, game play wise, than most LWS4 or LWS3? There was a major change in game play between core and HoT. Then HoT and LWS3. Ever since, it has been mostly the same. I dunno what could change here, but nothing have.
