The issue as of right now is the lack of activity in the Elsword section. Without a high member count within that section, it becomes unlikely that many members would do continuous contributions.
The Wiki Team can only create templates and basic pages at best. As of right now, none of them specialize in Elsword information. Without any Wiki Staff involved in it, they can not help easily unless you are in constant contact with them on how some things should look, especially if you don't know how to create templates.
Paul (NoeJeko) also has to create the initial Game Wiki, which takes time and would be wasting his time if barely any contributions are put forth.
Many of our past Game Wiki's have been in the same situation. Members have a hype to contribute and make the Wiki the best they possibly can. Once the hype dies down and people start getting bored, people stop editing the information.
