you do have some good points there, but...
1. its supposed to be a hard boss to summon....
2. you are correct in the drop rate of their heads, maybe the spawn rate should be boosted a bit
Both of these exact questions are answered in the FAQ, with almost the exact phrasing you use. Maybe you could take a look, and that would answer your (frequently asked) question?
also, the nether itself is actually a bit boring outside of fortresses, maybe something could be added to the nether outside of fortresses?
Which is what this change helps fix. The problem you describe is exactly the problem this change is a step towards rectifying. Does it fix it all the way? No. But it does help fix the incredibly skewed distribution of content between fortresses and the rest of the Nether. In the words of ShadowKreach:
There's a whole freaking dimension to fill, and they choose to put most of the content in a comparatively minuscule building. Why?
also im not sure it's such a good thing to say you have a bunch of supporters, some people may come across it the wrong way and think you're bragging about having that many supporters.
That's certainly a valid concern, but it's also one I've already answered, just like your above two concerns. Perhaps you could take another look at the post, and see where I might have already addressed your queries?
