Sorry OP but I'd dislike/neg rep if I could.
The biggest feedback was engineering was not accessible for the part timers and non hardcore players! it now is and it's much easier to do and obtain upgrades.
This new way of doing things makes it so much easier with the materials trader.
I don't think you know what i am talking about. I am talking about the FEEDBACK FORUM, not the feedback on engineers before. And it is a simple mathematical fact that "part timers" and "non hardcore" players will suffer the most from the new system. Before you could get decent g5 modules with 1 or 2 rolls. Now you need 20 at least.
