I think the game would receive many more sells if architecture pieces were sold as sets (like how Conan does it) vs trying to sell them as gacha packs. I bought a few of these packs, but its frustrating trying to collect the pieces for an entire set, only to end up with a bunch of duplicate pieces or ones that I dont want. So then I have to wait until I reach a certain level to acquire these pieces on the marketplace. You are missing out on many sales. I would be buying sets, but I refuse tobuy any more of these random packs.
Additionally, if you offered more architecture sets, I think players (especially in pve) would spend money on these. Plus they are only cosmetic items that wont effect pvp game balance.
