Exactly, my point is validated. Thank you.
Just to prove your point though, on mods being present on the various special levels, I looked at the wiki (assuming it's accurate) and here are the various mods which are available on a normal (not a challenge) game:
Chained Court: 2 agility mod packs
Hell's Armory: 1 agility mod, 1 power mod, 1 bulk mod
Mortuary: 1 power mod, 1 bulk mod (it should be noted that the mods are in separate corners, making getting both very difficult)
So, assuming you enter all these and obtain all the mods therein, that's 7 mods. I like to think it of it as 6 though, as you'll pretty much always use one of those agility mods on a pair of boots, which doesn't require any fancy traits at all. Also, you might not use the bulks on weapons at all, as using them on armors is much more appealing, so now it's more like 4 mods: 2 power and 2 agility. You might be able to make a really good, single weapon with those, provided you had the foresight to even go for whizkid in the first place, and that you had the good fortune for Hell's Armory to even appear AND that you had the stones to tackle the Mortuary just for those two mods.
With this in mind, I suppose that you'd be able to semi-consistently build a 1 power/2 agility plasma rifle before the mortuary considering that Hell's Armory had the good fortune of appearing, with the 1 level of whizkid which the ammochain master trait requires. With ammochain, sticking with the one plasma rifle, and funneling all other mods you get courtesy of the RNG is practical. In any other build though, which requires that you be adaptable and well-prepared, leaves you with a scarce amount of mods providing the RNG is being stingy as it usually is. So, in my mind, it's not consistently practical, which invalidates it's existence as a trait. I don't think I need to tell you that this, in my mind, is a problem.
Back when the advanced weapons were still around, I'd look at mortems that used them in conjunction with Whizkid to give them an OBSCENE number of mods. Looking at this, I could only think "Man, what sort of Wiccan witchcraft did they use to get the RNG to give them the exact advanced weapon they needed AND all the mods they needed in a single run?", just because in all my playing of the previous version, I had never encountered a similar scenario. Something requiring brute force repetition to get exactly what you may need in a run isn't exactly what I'd call balanced as far as traits go.
I'll probably make a thread about this, as this isn't a perfectly appropriate place to discuss this.
