Again, most people aren’t arguing about what was or wasn’t promised, people are just frustrated by an outdated/poor design in terms of RNG % and farming methods. You clearly don’t feel that it is outdated for whatever reason, but a lot do. For some reason you are essentially running in to each thread and telling people that they should not feel the way that they do over a random point about Gearbox making promises, which is not remotely relevant to whether the loot system is good or bad.
For example, if Sony releases the PS5 without an HDMI port in 2020, that would obviously frustrate a lot of people because it is a bad design in 2020 in the eyes of most people. However, some would not care. However, whether or not Sony promised an HDMI port has nothing to do with whether or not people are right or wrong to voice their frustrations about a perceived design flaw.
Tldr: BL3 loot system = flawed (in my opinion). Me = voicing the issues I (and others) have in hopes of improvement.
Nothing wrong with that (when not done in a hostile manner).
