Am I the only one thinking that Pecking Order gives too much bonus? And it is much guaranteed that “competitive” players will use Plasma Rifle to easily get this.
To be honest, some waves grant this bonus much more than some mission-wide medals. Players are also motivated to use superweapons/consumables since the points given are much worth than the value of those medals given off.
On the other hand, Multi-kill still gives a linear bonus, pretty much no incentive to kill all chickens in one go.
