If I played Final Fantasy 7 and all I used was Knights of the Round Table and then cried "the game is too easy" it's my own fault.
If you choose to make the strongest items in the game and then use them its your own fault son.
For RP purposes you are choosing to play an Artificer, someone who creates Legendary Artifacts far stronger than anything a normal mortal can create. You chose to do that.
But if you decide "I am no craftsman, I will go forth and seek the Artifacts that have been created by greater people than I" than you gotta live with a higher level of difficulty for doing it.
If you're crying "I only want to play this game through once and it svcks that I didn't get to be the strongest possible combination" I have no sympathy for you.
In the FF7 example though, it really isn't as strong of a RPG though. All your characters have roughly the same "build" each playthrough. Your only real options lie in accessory style gear, and materia selection. Which obviously should be used to greatest effect. Some decisions are indeed superior to others, sure. In Skyrim though, we're offered 18 different skills to focus in, and recommended that we focus on as few as possible.
Oh no, I'm quite happy with my first playthrough, in fact I stumbled upon how powerful crafting can be naturally. At first I smithed for the fun of it really, and then after dabbling in enchanting (and realizing I wanted that dual effect perk), quickly realized that I could enchant +smithing, and it went downhill from there. I find that enchanting +alchemy gear for the sake of making +enchanting potions, so that you can loop that to achieve perfect +enchanting, and +smithing potions, to be excessive. The end result is, in my opinion, not cheating, but it most certainly is world shattering.
My issue is that now I know, that when I play again, if I want to be the best archer, I am simply best off improving my artifice skills as a means of achieving that goal. Not only will I end up with something stronger than had I focused solely on my own archery skill, but I would also have the room to improve that archery skill when I was finished.
And no, if I am RP playing an archer, then it would be a matter of coming to the realization that crafting is simply a better means of becoming a greater archer. That having the coolest toys actually does make you a better person.
