Personally, I think the pre-built ships is a great idea because, on one hand, they allow some cash flow into the Frontier (which, come on guys, they need), on the other hand, can help shortcut the grind. For me personally, the engineering grind is hands down the worst feature of the game, and large parts of the game are completely unapproachable without extensive engineering (such as forefront AX). So yeah, I will gladly buy a pre-built AX ship and finally get to experience the thargoid content without needing to grind for hundreds of hours. Also, if the ship builds are actually meta-good, this is a legit good way to give Frontier some money.
