Because, Stefan.
But seriously.. Unixmad..
Guys do you get how much Stefan makes? He probably regrets not making iPhone servers earlier. As much as he enjoys money, apparently he doesn't like the idea of 1 person, aka moneybags, buying bars for their whole gang and ruining it for everyone. That's one reason I heard. Also, a lot of items are meant to be special. Why give them away? What I don't understand is why buy all these melees and gani items if you just wanna "trade" them away. If they made a trade/drop system items like that would lose their value because they wouldn't be hard to acquire. Rares are rare partially because you don't know who you can trust with a trade.
Also, staff really can't help everyone who got scammed. Thousands of iPhone players are on graal compared to the few hundred on pc. The staff team are all unpaid volunteers, and there isn't enough of them to handle every other persons complaint about scams.
You bought it, you dropped it, your fault.
But a drop any item/trade system would make a lot less people complain either way.
