That is part of it. I hadn t thought that way and i like that declutering of the shop.And as for the weapon shop rotations, I see what you mean now. I should be more "Smart" and sell items that you can actually afford.
Lets say hipothetically, that i am an inept again, and for this caracter i want to try quarterstaf (if quarterstaff ain t for inept imagine it is) because i ve trained a lot of quarterstaff and i am rusted with other weapons.
But in my allowed starting weaponry quarterstaff ain t there, nor in the shop.
I will be dependent to my item rotation luck in the shop.
Why not let all inept weapons availiable in the shop. (inept only, for the rest of the ranks it stays as it is).
A little boon for the beginners.
