Keep in mind there is no such thing as pre-pulling. SE has gone on to say that once a hunt is found, it is up to the player(s) if they want to wait for others, but are under no obligations to do so as it falls under the same category as any other open world mob. This means they are free game. On the flip-side, resetting hunts is a report-able offense.

Asking for these things in light of SE's stance means you're probably not going to get them. If you're simply missing in getting full participation, it goes off aggro. A healer that doesn't DPS, but spams AoE heals and over-heals like crazy will pull full participation credits. A tank in tank stance will pull full participation (usually), even without a party. Poor DPS need to stack on damage quickly if they want full participation, but as long as they have a tank and/or a healer that are doing the previous, the group should get full participation.
