While exploring reasons why this role was underplayed one of the things
that came up was its speed. It is dreadfully slow - to the point where
defenders are able to force an engagement against Synthetics. There is
no chance to run from anything faster as a Colony Synthetic. Making it
have to fight often.

Lowering the resistance is something devs wanted, and for gameplay this
is good because a Synthetic shouldn't be forced into a fight unless they
have no other option. Especially not by something as slow as a defender.
Might tweak later but council generally is in agreement with this
change. Little by little!

For the CQC, a Colony Synthetic is not as advanced as a Shipside one,
but still is more than capable of outmanuevering a human. As for the
hilarious UPP Pvt being better than a Colony Synth in CQC I will make a
separate PR

For Fireman, a Synthetic can bend metal, move cars and do many other
'superhuman' feats of stength, they should not struggle at carrying
people, especially shouldn't be worse at carrying people than a Marine.
It's from 1 to 3, to represent the strength yet aging capabilities of
the Colony Synthetic. @morrowwolf forgot this one

# Explain why it's good for the game
Less resistance is something devs wanted.
Allows Colony Synthetics an option to avoid certain engagements as now
they are able to outrun some types of Xenomorphs off-weeds. Defenders
should not be able to catch them offweeds.
A Synthetic should have no problem carrying something as light as a
human being - they especially should not have MORE trouble carrying
someone than your standard human doctor.
