There are a variety of ways to play GD when it comes to item farming. There’s fully self-found, there’s self-found + trading, there’s modded drop rates, there’s GD Stash, and more ways than that I’m sure (maybe someone out there uses custom crafting? )
Personally I like the second option. I want to play the game as-designed, and part of the design of the game includes a multiplayer trade option. Plus I get to meet some nice people through trading.
I’ve heard some concerns about trading being a risk, because what’s legit for one player isn’t legit for another. The best example would be modded drop rates - some people using these would consider their items to be legit, while many would consider these items as not legit.
But I’m here to make a differing viewpoint to the “legit vs non-legit” argument. What’s the difference between one modded droprate person and two non-modded droprate people? If the community were larger, there would be a higher chance of finding someone with the item you’re looking for. As it is, it’s a pretty small community of traders, so if a few of them use modded droprate, it’s like the community is a little bigger, no different. The end result is the same: you found a person who got their items in a legit (to them) way, and traded an item or mats for it. Unless you feel like you have made a large personal contribution to the size of the community, I say it doesn’t make a difference how the person trading you an item farmed their item, as long as they believe it was farmed legitimately.
Post Script:
Of course, use common sense when trading with people. If the stat rolls are all perfect, chances are they GD Stashed it. Even if they didn’t, why would they give up a perfect item? Same goes for insane greens. I seriously doubt that anyone has ever crafted two pairs of “thunderstruck stoneplate greaves of kings”. If someone has had the insane luck to craft one of those, they sure aren’t going to trade it for anything.
Also, just look at people’s behaviour. If they have a list of items that they own, they’re probably legit. If they have any item that you need with 200 hours in the game, they’re probably not legit.
