It provides a new taste to the game and will provide more of a custom survival experience to bring more players

Maybe you could elaborate more on your idea?

Personally, I believe that’s what the Zulrah & Herobrine bosses were added to the gamemode for - to give players an extra, custom challenge with (somewhat) decent rewards for defeating them.

As well as this, there’s PvE battles, called ‘ancient trials’ (/trials) for donators on Survival.
