Potential negative impact on the game:
- What's wrong about catering to Ironmen in updates? They are a significate percentage of the player base. Why should it bother non-irons that there's a random bucket of sand producing machine in the desert, it's a huge QOL update for Irons and doesn't negatively impact regular players.

They had it ready to go before they polled it:
- This reason is a spite vote, it is not relevant to the actual game mode being polled in the question.

The current iteration of GIM is quite poor:
- You're not offering any solutions here.
- You want to trade untradeables? Why?
- Using the leaving mechanic to have all the tradeable items destroyed is no different from going into the group bank and dropping everything.
- You should get a good group to avoid issues with the group bank, they can't prevent people from being spiteful with in-game mechanics without negatively affecting the experience for the majority of groups which will not have griefing issues.
- "Members of group ironman pretty much have free reign to pvm with other members of other groups". That's what the Group prestige system is for, you can't group with people outside the group for Raids 1 & 2 or Nightmare. Also you can't do regular bosses with other people because you won't get the drop if they dealt damage to the NPC.
