Let me ask this:
If they were to offer the Tier 7 ship parts in one complete package for $5 on the CM and also offer it from a Vendor in game for 500,000 credits, would it still be a problem?
Not sure where you're leaning with this but I'll bite. No, it would not be a problem. The cost would be more consistent. Right now the cost between gameplay hours/effort/hoop-jumping and real world money is so imbalanced that anyone who values their time will be compelled to simply buy these items and move on. Possibly feeling scammed in the process.
