[2018] Influencing loot pools

Originally posted by NoGhostRdt

So I know that in the stream the devs said that there would be over a hundred different types of inscriptions with loot pools separating them. But how big are these pools exactly? Are they so big that it'll take 10 years just to get a god roll? Because as far as I know, you can have up to 4 inscriptions on legendary gear. (correct me if I'm wrong) The amount of time it'll take to get 4 good rolls on one gear and the time it takes to get a gear makes me concerned that I am going to get one god roll a year. So there are two scenarios: (1) Each loot pool has an insane amount of possible inscriptions or (2) each loot pool has too little. Personally I want it to be the first choice, but if it is too big, then maybe perhaps have some kind of item that influences the type of inscriptions you're more likely to get. Like some card that you can set your most preferred rolls like melee only or thrust only. Idk, what do you all think?

Edit: I'm all for taking a long time to get god rolls, but at the same time it shouldn't be so long that it feels like it'll never come.

Edit: I also don't want it take so long because of the fact that you can have multiple different kinds of builds. They emphasized how builds vary wildly, from melee build, gun builds, ability builds. I want to be able to get some god rolls for multiple builds in a long, but timely, manner.
