I can only agree on that, after they added the most basic Stuff we need. The basic features have a higher priority.
Very true, but then again musical instruments are important for all RP, atmosphere and for events.
A very needed basic in any MMORPG, even more so in a sandbox.
Same for anything craftable like tools and utilities. MO lacked heavily in this department and meant the game had lower amount of players of that kind than it should.
