I hope that if the 10% loss with module sale happens that the entire purchase process is revamped. Instead of buying one item at a time. With. Lots. and Lots. of clicks... make it a system that works like a shopping cart with a final review and a checkout screen.
Allow the players to 'preview' the purchase by fitting whatever modules are desired. Then, at the end, before the player leaves the outfitting, there is a commit changes with a review page similar to the insurance rebuy screen. This screen totals the cost for all changes and allows the player to deselect components should it be too expensive. Better yet, a graphical representation of the changes and how they impact the ship performance would be superb (and not I'm simply dreaming, right?)
Can you imagine driving into the shop for an oil change on your vehicle and having to pay for each service one at a time? That is outfitting in ED.
Current outfitting:
Oil filter selected, confirm, are you sure? confirm. Cha-Ching
Oil selected, confirm, are you sure? confirm. Cha-Ching
Oil disposal fee, confirm, are you sure? deny. ERROR MUST CONFIRM, (drat) confirm. CHa-ching
Taxes, deny. ERROR this will revert all services, confirm? (drat again) confirm. Cha-Ching...
etc.
Proposed:
Oil filter, check. Oil, check, disposal fee, (grumble) check, Taxes (meh) check.
Confirm purchases?
Confirm...
Cha-Ching.
