The good news is, if you honestly believe you have to camp vendors just to keep up to same level enemies (tip: you don't outside of Tactician at all), you can play four Intelligence based casters. They don't really scale with gear nearly as much as the physical builds and do just fine.
So the 'good news' is that you have to play a specific type of party makeup to even attempt to get away from the item scaling problem? Go white knight for terrible systems somewhere else, nobody's buying your bullshit here.
Pretty much every merchant NPC starting at Act 2 will sell all type of gears covered. Just in Act 2, the town area and the paladin camp that can be accessed without any fighting will cover every type of gear you need.
Like the Lute girl can be persuaded to sell the best bow and the paladins sitting at the bridge will sell the best 2H weapon pretty much every time they restock so you never face the issues always updating your gears every 1 to 2 levels.
The nerfs pretty much force you to at least interact with the npc with even maxed out lucky charm + lucky gears. You just need to know who sells what on Act 2 and Act 3 if you really want to have 100% update gear.
The real issue is the gears scaling though, mainly Legendary gear and Divine gear having too much stat on them. They should have nerfed those instead of targeting lucky charm.
