I thought that it would be useful to check the repair costs for 'normal' play.
I'm level 30 Sniper on Tat.
I repair to zero my costs.
I go out and fight 11 mobs 2 levels below me, neither myself nor my companion die. INo Elites involved).
I repair again - the cost 1,720 creds; more than I earned from the kills.
I know - that's not a lot of money but, surely, given the circumstances that's disproportionate.
