There’s nothing wrong with this. The issue with the guilds breaking up over HMs are the fault of guild leadership. They formed the guild without a specific vision. That, or they’re trying to take a casual guild and make it hardcore. Both usually lead to the issues you’re talking about.
There’s nothing wrong with this either. Think of it like this. Some people view this game as going for a light jog. It’s enough to get the endorphins pumping, and you feel fairly good after. But some people want the accomplishment of finishing a marathon. Which is also fine. The issue is the light jog people, and the marathon people, are in the same race. Which again is on guild leadership.
