I am playing a Dark Armor/Katana scrapper on SO's only. No seed money, selling all recipes and white or yellow salvage. (keeping the orange salvage and rare recipes that drop) I don't even allow her to combine enhancers.
She'll never do +4/8, but that not the reason to play her.
She is currently lvl 38 with all lvl 40 SO's, about 1.8 mil in reserve influence. She plays it safe at +1/1.
At level 40 she will first enter Ouro and then the university, then start building recipes. She has been stealing Hero Merits out of email storage so she can purchase full scrapper sets with them post the lvl 40 change up.
