I agree that some ppl may rage quit due to rng, but the same you may spend 200k honor and get nothing you can spend 6k and get full gems in a piece of gear, anyway, not everyone is supposed to have full gemed gear or even divine gear for that matter, there is a break point for geming and regrading so some lucky few willget above, its about rng, if you want your hard work to pay off go move pack in safe zones.
In your point about lack of pvp, "Lack of pvp. After the initial boom, and people start getting their gear full socketed, pvp dies off.There is no incentive to just go out and randomly pvp, honor doesn't have nearly as much use" and you want to make it easier to get fully socketed...
And dunno about the whole divine buffs thing, you dont need luckies to get divine gear and divine is not that much ahead of the rest, celestial is the less you should have without any effort really, you get celestial armor set from gha and the weap is not hard to get to celestial, talk about epic/legendary gear and then we do have a serious gap, but not divine, if you are using luckies at unique it beter be some really nice delph/ayanad gear or you are doing it wrong by not blowing up celestial to aim for epic.
So, less luckies in the market means less ppl getting higher grade gear, wich at this point is fine, everyone has the same problem so everyone stays around divine and some lucky one goes above, but thats what RNG is about, a lucky few get ahead, same with gems.
I will play along with your "preventing divines from entering the game", which is a weird reasoning to say the least, even if there were no more luckies entering the game, it is the same fate for everyone so everyone will keep playing the same way they do, actually the gear gap wont change much without luckies.
