the ever growing hit, Tree of Savior, has addons and is really hard to both find them and install them.
Tree of Savior is currently the most played MMO on Japan, and has a growing population.
We need a better support for addon creation and distribution on tree of savior, since currently there is none and things are just randomly posted on github and sometimes announced on 3rd party forums.
I think curse could make a profit from this needing market!
