*Less skilled players would take builder classes and tag along hoping for scraps. Nobody wants to see newb builders on their team, espceially not at the frontline.
And the gain is... ? Nobody wants to see noob builder no matter what he does. Salvaging noob is still cheaper evo point than shooting noob.
*It would discourage the human suicide runs where you wipe out as much of a base as possible with saw / flamer / grenade until you die from acid.
And how exactly are those suicide runs wrong? Remember, the goal is to wipe out the enemy base and then all alive enemies.
*It would encourage humans camping even more, because nobody will want to leave a corpse in the middle of the map.
Repeat after me:
The goal is to wipe out the enemy base and then all alive enemies. Camping after stage 2 IS BAD. The goal is to wipe out the enemy base and then all alive enemies. Camping after stage 2 IS BAD. The goal is to wipe out the enemy base and then all alive enemies. Camping after stage 2 IS BAD. The goal...*Humans would be able to salvage cash during the end game when the s3 aliens start slaughtering left and right. This would be great.
Have you ever seen something like that happening? I don't believe you ever have.
