Seriously you really think you can be lucky how many times and call that yet “luck”?
I call that probabilities.
I have surely more than 30 weapons really good… Shotguns of all types for 3 chars (1 zealot, 2 vets), Bolters, Helbore, plasma guns, dagger (zealot), combat axe (10-15 between the 3 chars), tactical axes (2 for the zealot, 2 for vets), heavy swords (mk vi and vii), flamer, colomnus and agri brauto, shredder autopistol, thunderhammer, crusher, PS (mk III and mk VI with PC / sunder / slaughterer), revolver (ok this one is bad anyways) etc.
If I consider what you wrote, I should never have all these weapons as, I quote your ironic sentence
What I said, and said it several times, is that you can obtain weapons you want easily… However, it needs time, and the time you have to spend on crafting is something that exclude de facto casual players and can discourage new players.
However, the locks, that you seem to focus on, are really not a problem if you act wisely.
Again, the problem is the time you need to craft something good , mainly cause we do not get enough materials.
