i think the order you posted is fine when we are all on, but when we are a few short, or just rookies on i think we should do snake-raptor fisrt, only because it is a no brainer, and we can do with 15.  plus as guys start to get fitted out, we will have a greater shot at higher bosses even easier.  otherwise the order makes since, hit the hardest bosses first when we are all stoked on potions, and our armor is still green.
