Echo buff only when there's a new player

That's because using echo is the norm because everyone else is. If the norm was changed to no echo it wouldn't make a difference to those that cleared before because they either don't care about farming it (just need to clear to move on) or the fight is already hammered into their heads that 10-25% makes no difference.


Thinking about how it affects the whole community instead of just your own group, it might be better for everyone?

I haven't the slightest clue why you think further restricting something that's already optional would benefit the community in any way.
