I'm going to go against what may be popular opinion and say like I like that all engineers now pay the same net costs to repair costs. An increase in repair rate should be just that, repair RATE, but still cost the same amount.
That said, now that engineers are paying for repairs properly now, I can see why Golems are too expensive now.
I have not had enough playtime since the change to make an opinion on whether base repair cost multiplier overall should go down a tad. IIRC, the default base rate is .25, which honestly seems about right.
EDIT:
Actually, that guy who tested repair costs (and discovered the bug in the first place) care to do it again, or at least tell us your setup? It would be nice to see what the repair multiplier is now.
