Early Pulling - Is it wrong?

[MomomiMomi]

SE made it so S ranks and most 50+ A ranks require a large group to kill. There is benefit in waiting and no benefit in rushing. First come first serve, provided they have backup... It's clearly meant to be a group effort and early pullers clearly spoil that with self centered actions. The intent of high rank hunts is max participation for mass rewards.

The A ranks were meant for a single party. I wouldn't call that a large group.
