I always thought they should make HNM's rarity per person / group rather than a specific time on the server..

Ie.. you could only fight a specific NM once a week or once a month..

like an extended wait period for an enm....

maybe could implement an elite fov regime style pop system.. where you need your key item to assist in the fight.. and if you don't have it can't cure others or engage the NM..

for example you go to fight behemoth with your once a week key item. Win or lose you can't fight again for another week.. nor anybody else who assisted you would be able to fight..

If it was like the fov elite regimes.. outside people couldn't cure you.. and people couldn't join halfway.

With a system like that.. NM's would still be sufficiently rare.. and the drops they have would still be valuable and an "accomplishment"... but people wouldn't have to worry about competing against a bot
