As much as I enjoy the idea of people being able to help without killing the drops, I feel games that are centered entirely around Instanced Content are hollow and lacking in the social aspect that are the sole basis for playing an MMO. If you want to only play with your friends and never have to compete with others then you should probably be playing and offline game or perhaps GW or DDO.

You have my support, with the Insistence that there should be a help option that does ruin drops.
