Think there is portals you can enter a shadow world to the normal world where PVP is allowed it should be filled with same mob as the normal world and same NM HNM.
the diffrence all mobs aggro in the shadow world the NM drops star version of the drops in the normal world and the NM should have longer repop timer.
Then multi fight will be against diffrent linkshells and NM at same time the drops should be same as in the normal world but star rated.
The Party or person who do most damage to the mob NM will got the drops.
Make the NM pop in outer skirts from where you enter zone you have to fight your way to the NM and on the way its not only aggro mobs other linkshell maybe attack you when you are in the situation fight the beast tribe on way they see there chance attack you when your linkshell engaged allready with little to many beastmen.
this content could bring in alot of new spells abilities like invisible to get to the NM a small group rangers move invisible to the area where where the NM should be instead of the bigger group who fight there way there detection spells abilities to find the other linkshell hiding close the NM.
Example the NM pop in a orc village first you send in the scout ranger invisible see if other LS there fight allready if NM upp you decide clear a small path tougher mobs to pull in the NM in a better zone there other LS have to kill the tougher mobs first to reach you.
And its easier for your small group defend if other LS try reach and take over your NM terrain and NPC mobs can be used to protect your claim if you fight wise and use terrain maybe also type of gates guarded by npc.
If you have claim of an NM inside the willage the outside NPC guards repoped to get chance for the other LS to reach you they have to fight the NPC guards outside gate when they try you help defend with ranger and mages from castle walls inside willage if you was smart enough clear them first.
Maybe the other LS bring in some invisible ranger to try hold you down to there main force arrive to the battle ground.
Alot of tactics diffent fights will make something good to this game then a zone like that realyy will make the equipment usefull when stats is fixed on it
Every time you enter the zone action is garantee will you fight your way to the NM will other linkshell or players kill you on way.
There will involve tactics should we group up with other linkshell we meeting or fight them over the drops same people needed to defence the claimed NM from aggro mobs or other linkshell trying to attack same NM.
Maybe you team up with some other people from other linkshell to fight your way for the reward.
just a idea to get some random action where anything can happens if you are tired for action just return to the normal quiet world =)
this gonna make alot of things the game missing action tactics zones where people move around bigger groups will just fight there way to the nm smaller group trying move invisible the zones will full of action and tactics fights
