My Idea is perfect for your type of play style and Mine.
But if you want an exclusive trophy from out claiming an NM that respawns every 24-74 hours then that trophy needs to be a Mog house kinda Trophy where u can put it on for decor or something to show how you claimed the HNM in order to obtain the item that extra bonus item. Maybe it could be a Statue of the HNM you camped? Something like that for show off but, Not something that is a gear that is very valuable and epic where a lot of people like me also want it badly but cannot afford time to get it and will not experience it due to this limitation.
I am against this mainly because I want to also enjoy contents that I would like to participate and get a good chance in getting things from them. I feel accomplishment when I get things done and my character improves in every aspect when I log in for the day. I don't feel like im wasting time and that is the feeling I like when it comes down to Abyssea Pop NMs for seals etc.
You may not like this game right now, But I LOVE IT waaaaaay more than I did before.
This is why I discourage any Old HNM system where exclusive epic gear comes in and I will never get the chance to get the item I want from them.
