Hey guys, lets add RNG to loot now, so now you have to spend even longer to get the appropriate gear to actually do content cause RNG hates you!

Some RNG is fine in mechanics of a fight, but not fine in gear. There needs to be a stable base somewhere, and having to deal with RNG stats that arent optimal is going to hose people. This gets more important when its pretty much expected you wont get a 'perfect' roll on loot, and are much more likely to get sub optimal gear. And if its just for funsies/random drops, then you can bet most people wont spend excessive time on it. Theyll just go for the gear from NPCs or bosses thats guaranteed to be good.
