So, I enjoy endgame in MMOs. It's usually pretty fun, and running group content that's entertaining is a good time. If the group happens to be a bunch of people you enjoy spending in-game time with, that's a bonus.
Unfortunately, being successful at challenging endgame content takes time and effort. Just like improving your skill with an instrument, there's an investment/reward element. You seek outside help, you get critiques, you work for it.
