All of the SCO-Ready ships become available in game, for credits, for everyone. Does 3 months or so of early access render all other ships surplus, or the new ones as PtW? When you buy a ship, you really only get a few months of access that peeps who won't buy ARX miss out on. That swipe of the credit card is nullified in short order.
Knowing that some of the pre-made ships may have A rated modules, hardly the top tier gear in ED, none of these modules can be used on any other ship, nor does a redeploy replace engineering on those 'free' modules. Who would sell a ship with engineered modules, for the same ship without? So the redeploy trick leaves people with a capable ship, but hardly a PtW gamechanger. When does a gimballed pulse/MC load-out ever win in PvP?
You really have to look at actually how ED works, to have a proper view of the impact of pre-made ships and early access releases. Which I submit the OP just does not have. The OP is just arguing from basic understanding of gaming, but doesn't really see how the pieces come together in the end. Maybe, with a sale or something, the OP might have a dip into ED, and see that our experience in game gives us the right perspective on this issue.
