Why does it matter if people come in after your guild clears out fear? Are
they hurting you in any way?

To be honest, you say how much it stinks to break the plane (deaths and
time) but then criticze others for not wanting to do it themselves.

Given: Guild XYZ has broken Fear. Guild ABC wants to hit fear later.

Choice1: Go in when we're ready and kill stuff as it shows up.

Choice2: Wait till later then do the whole break thing our selves.

If depends on what you want. There is nothing wrong with either choice, its
just a different play style.
