Made a new request thread here:
Why not setup a system to avoid mass teaming up, so whichever faction has the least members will be buffed, and the faction with the most will be nerfed. This would balance out the odds of victory / defeat.
Please see the date of the post 
Other things came on my path and I’m not developing this project.
I was intially making it for my own server and for a friends server but his server shut down and I’m no longer interested in factions.
If I would have done it then I would have been announced it here already.
I’m sure there are other people looking to improve Factions and that many alternatives will be created since it’s the most used gameplay plugin.
Hadn’t noticed that. Thanks for telling me.
If anyone ever reading this has an interest in this (OSGi & Sponge), do check out my GitHub - vorburger/ch.vorburger.minecraft.osgi: OSGi-based Minecraft Server plugins (spongepowered.org) project, just announced over on OSGi - a dynamic plugin reloader type mod useful for development. (Just found this old thread by search for “OSGi” on this Forum.)
Still a bump and kind of pointless since this is literally 2 years old.
