The plugin system is good. The functions and possibilities to make dungeons are endless (and will be even more with future updates), but the lack of some basic functions are bothering me. You can't disable global announcement of deaths (all players in the server receive it, not only party/dungeon members). You can't translate the messages AT ALL, not even the prefix. Integration with Party and Friends would be excellente too.
In short, the plugin is receiving constant updates, and I read every feature request and bug report I get, but I am one person and can only implement features so fast. This isn't my full time job (yet) after all. :)
