I think it might be worthwhile to make the preorder gear caches a lot harder to get to. The gear in them is end-game or near-endgame quality (the Stinger sword is arguably the best single weapon in the game, since it has such a high Piercing damage value and is coded as a shortsword; another cache has a nurnberg plate cuirass!), but the chests are right out in the open with no surrounding hostiles and four of the five aren’t even locked.
I didn’t realize how powerful the chest gear was and ran around grabbing it all while in the middle of “Ginger in a Pickle”, and as a result my character got so overpowered so quickly I ended up restarting.
All told, I’d suggest retuning those chests so they’re a little harder to get to – maybe put some bandits around each of them or something so it’s not a pure cash grab.
I’d also suggest considering tuning down the Stinger short sword – it does more damage than the best two-handed longswords in the game, and you can use it with a shield with no penalty!
