How does it work exactly? Are members of warring guilds perma grey to each other? Or is it just that they wont go grey but initially appear blue? What about the guild tags? Are there more advanced mechanics behind it (scoring etc)? In general a guide on that topic would be great. Couldnt find any in our guide section; not even a more general guide to guilds.
They're orange to each other, no score, no trammy rewards. It can be used if you want to pick the kind of people/templates you want to pvp against, for example ppl back on OSI not warring guilds with dexers et cetera.
Everyone you war will be orange, just like in ant pvp outlet those characters orange to you are open to all negative actions. Unlike factions you will still be able to perform positive actions on them as well (ie res and heal).
