I agree! *wait for content*
More seriously, you have to keep in mind that the engine os old, tools to make the content has disapeared (even we have some little limited tricks), and making things takes ages.
We already added few content in the client and edited some : door size of forts, original dyes, lava texture, water in nordland, DOk and WP shield models, haloween cloaks, christmas decorations, icons, logo... but as said, there are things we are unable to do atm, and some we just understand withotu having the whole process or tools to edit.
Spoiler : We made from scratch some weapons set for each class (around 40 weapons and shlelds) (all credits for Ferrile, AustreV, Gojirawar, Machinea, Yali...). They are ready to be pushed in client. They still need names, maybe stats (unless we use it for appearance only), and a reason to be, but you have to know it took more than a year to do it.
