OK, so this new drop system solves the problem of calling dibs on items/item ninjas. That's nice and all but why would a capable player who understands math, play multiplayer in the first place? In order for us to take advantage of the item ninja problem being solved, multiplayer needs to be worth playing. Let's fix this!
We currently have two problems when it comes to items.
Problem: The item balance between solo and multiplayer is way off. Solo is far superior to multiplayer because you get more items in less time. In other words, if you want items, and you are capable of soloing, you will generally get items between 3x to 4x faster by soloing. If you have additional members in your party, regardless of which drop system you use, it means less items for you. With 4 players, on average, each player will only get 1/4 of the items, compared to solo. If you want items, and you are capable of soloing, there is basically no reason to play multiplayer.
Solution: Better item balance between solo and multiplayer. We need a drop system that will give each player their own item, and at a decent enough rate. The goal should be a game that favors multiplayer, or at least a game where you can find items at roughly the same rate regardless of how many players are in your party. Ideally, the DAR would remain the same no matter how many players are in the party, which would mean that the game actually slightly favors multiplayer. But if the idea of an online game favoring multiplayer is crazy for some strange reason, assuming that each additional party member will speed up the quest clear time slightly, a slight DAR reduction could make sense. If it takes 60 minutes to get item X solo, it should take 60 minutes or less to get item X with 4 players. Adjust the numbers as needed to get the best balance.
Problem: One person using multiple accounts to get items faster. This problem has always existed and will continue to exist regardless of how the new drop system works, but it could potentially be worse if we let players quad box with a multiplayer friendly drop system to get items faster. New accounts are free, you can run multiple clients on the same PC, and one controller will control every client. All of these reasons make it extremely easy to exploit the game and get items way faster than normal. I've solo'd with 6 accounts myself and I can get 90 Luck mats or 12 Glide Divines in 1 HH.
Solution: Restrict one person from using multiple accounts to get items faster. One way or another, this needs to happen. Maybe it can be done through software, by reducing the number of accounts allowed to connect at once from 6 to 1 or 2, or disable support for multiple clients on the same PC. Or we can just have a written rule that says something like "One person cannot use more than one (or maybe two) accounts at the same time to get items faster", which means players could still use multiple accounts for things like item transfers or visiting a different lobby. If we allow two accounts, people could still use it for things like section ID and buffs, but more importantly, there would be room in the party for other players, so true multiplayer would still be possible.
Personally speaking, until these problems are addressed, I will continue to solo with anywhere from 1 to 6 accounts, because that's the best way to play the game based on its own rules. I do this because I want to be strong/good at the game, not because I enjoy it. I actually prefer to play with other people, because multiplayer is much more fun and interesting to me. Please fix these problems so players like me can enjoy playing multiplayer and still feel like we are playing the game in an efficient way. Thank you.
