You like the bike? Go for what ever upgrades you want. There is nothing wrong with the frame's construction.
Same with the bottom bracket shell.
The funny thing, although castings were considered the upper-end choice ("more precise", etc.) stampings actually have better fatigue resistance and will tolerate cold-setting more than their cast counterparts.
Like the other say, all that matters is that
you like it.
