Forums are mostly for criticism and discussion about issues, for every game pretty much.
It's good for the game and the community.

As for whats good? Well I returned almost a month ago and I do love the comfy atmosphere in the game. Played WoW for a while, but its just not as comfy to spend time in. I feel like WoW forgets to have fun with the quests and other activities. The soundtrack in FFXIV really made me think why most other games have awful soundtracks. Final Fantasy soundtracks aren't as good as many make them out to be, but they do have an actual soundtrack. Not just non-confrontational ambient music. There are actual songs, lyrics, proper pieces of music that are both memorable and fun to listen to.
Too many games just have that boring, forgettable backround music that I end up turning off overtime.

Also the vast variety of shorts, panties and thigh highs in my retainers inventories is magical at this point. Never too much of those.
