They are working on it but not much at all.
They aren’t tweaking classes as far as i know.
Crafting is good for foods which are used in raids and dungeons. (health, stamina and mana). They can also be bought on the tradepost.
There are still people using the crafting system, mainly W3 crafting for the ibis weapon and T3 crafting for some of the best weapons in the game. (sogoth 2H, bugged with way too high white hits) (1h as offhand for conqs and burbars) and protshield for tanks, poms and tosses).
They are currently working on something, they haven’t reviled what it is jet or when they will release it.
My personal opinion is not to join the game if you are waiting for new content because they don’t release new dungeons and raids that fast. But if you haven’t done all the content or nothing at all then theres plenty of stuff to do.
Guildcity gives you small buffs, but with the low amount of players i think it might be better to join a guild who already has one. There are many small guilds out there who has full T3 guildcity with all the buffs.
