Yes I 100% understand that! It's hard to come up with something never before seen and execute it really well, that's what makes grasping the full potential of GenPVP servers hard.
Perhaps another things that makes GenPVP servers not as fun as they should be is that usually the staff team of a server isn't really open to constructive criticism, I've had my fair share of mutes / bans from servers because I was suggesting better ways to do something, and I don't blame them either.
Sometimes it's hard to tell if somebody is trying to be constructive or just criticizing your server without good reason, but I feel like server owners and development teams should be more open to their community, it's what makes a server the best in my opinion
