once we get to go beyond lvl 50 the crew skills and missions also need to expand and there is a simple way of doing this by using the old materials in new ways and being able to gather more of these materials, since it will take more make items. the break down should be by 40 rather than 20, so it should be 401to440, 441to480, 481to520, 521to560, 561to600, 601to640, 641to680, 681to720, 721to 760, 761to800. 401to440 it should be 10X 1st lvl material and a crit should be 1 lvl 7 material; 441to480 should be 10x lvl2 material and a crit will be 1-2 lvl 7 material; 481to520 will be 10x lvl3 and crit 1-3lvl seven material; 521to560 10x lvl 4 crit 3 lvl 7 and 1 lvl 8 material; 561to600 10x lvl 5 and crit 1-4 lvl 7 or 1-2 lvl 8; 601to640 10x lvl6 and crit 4lvl 7 or 1-3 lvl 8; 641to680 x6 lvl 7 or crit 1-4 lvl 8 or 1 lvl 9; 681to720 x4 lvl 8 or crit 1-2 lvl 9; 721to760 x2 lvl 9 or crit 1 lvl 10; 761to800 2 lvl 9 or crit 2 lvl 10. Every mission advance should cost 500 credits per advance, this would be a good thing for all of us that like to use our crafting skills.
