How about slightly re-adjusting the scaling (more hp for monsters) instead, so that somewhat similar points can be achieved without camping scavengers? Would this be an option? I've been doing some team raids the past 2 days. Everything is extremely easy but I can see that people are enjoying the teamplay in cox. Adjusting the scaling (hp increase per player added to the raid) wouldn't hurt to get better rates for teamplay.
Just to be clear, you're suggesting to increase the health scaling per person in the raid, right? I'd be open to that if people find that it's too easy and they can't get enough points, although that may need to be a suggestion on it's own, so that it can be explained to player's, and that way I can gauge the reactions of players to see if they'd want this change.
