Hello
Is it possible to make the neutral faction is attacked by mobs faction?
For exemple : A Faction "A" which is neutral relationship with Faction "B".
The titan of the Faction "A" attack the faction "B" without a faction put the "B" enemy.

Is it possible ?

It is possible, but I will not implement it in the plugin, since the current users of the plugin expect it to function as it already does. If you want, you can fork the plugin and make the modification yourself, for use on your own server.

Just change in the package Faction and class Faction Neutral Faction -1 ?

If you're using Factions 2, you would set this value to -1 from 0.

I am unable to import your project on my Eclipse :(
Can you help me or do the plugin for me please ?

I am in 1.7.10 with Favtion plugin 2.7.3

1.7 is really old and unsupported. There's been many bugfixes since then so it's not a good idea to go back to such an old version.

To give you an idea, this is the last 1.7 version.
