Title: Ironman mode

Description:
Me and my friends play this server for years and wanted a new and refreshing way to play it, so we started this challenge run, we are having fun trying out new builds and solutions to getting to the endgame in a timely manner with the limitations, an so the idea to spread it to the community arouse. This suggestion follows that and will be made in two parts, one for the community and another for a possible new official mode with some core changes. For the first part I will create a wiki page with a way to play this mode based on the current muh systems with the following rules.

No trade with players
No buying from players
No selling to players
No looting from other people's loot on the ground
No partying with other people
Use only a separate storage that only the ironman character can use

Or party mode with the following extra rules:

Create a fixed group with newly created ironman character
Trade is allowed between group members
Partying is allowed between group members

The core changes that I believe would be needed to make this gamemode viable in the long run and a official mode.

More runs per day for instances (5 per day)
Unlimited daily quests (for heirloom/muh coin farming)
Separate account inside the master that has limited access to shared systems in the master account (storage, cash shop, fashion points)
Ironman only shop to get items locked behind all damage necessary instances (for example Monster's Stone)

Why is this a good idea?

It creates a new and refreshing way to play the server for those that want to partake in the callenge, it incentivizes strategizing ways to use equipments that are mostly useless (furious) because you can just skip stages of the game by buying strong gear right of the bat (nebula and time dimensions)

What risks or downsides does it have?

For the first part of the suggestion there is no downside because it is more of an optin mode for people that want it. However the second part would need development time to create the systems to separate the normal mode and ironman mode accounts. The only risk I would say is people from the community not wanting or seeing the fun in this challenge run.

Additional Info:

I would say a similar/goal of the ironman mode I am envisioning is from Old School RuneScape
