The more I sat and pondered on the Family teleport system, the more concerned I have become, just wanted to open a thread where possible abuses can be discussed. If the proper restraints aren't in place, I believe the system could be easily abused. Not for the common "Summon guild/groups for raid" concept that everyone discusses often on the Discord. But for monetary advantages in game.
Now you can do this with a group of friends, or pay for an additional one or two accounts which will tie into multiboxing. I'll go into a bit of depth. Keep in mind this is all theory crafting as I don't have access to the alpha. But just going off what is known so far about the game.
Let's say your main character's node that you are a citizen of is rich in Iron ore, and a few other mats. Across on the other continent, or far off distant node, said node is low on these resources. Have a friend or guild mate that will always be on that side summon you, sell materials you have on hand, buy materials there to bring back that are rare at your parent node, and scroll/hearthstone back to your main node (if the game has a return to citizen node function). If the game does not have a return function, you would just need another in your family to be back at your main node.
Can be used as a p2w mechanic in game as well with multiple accounts. If there is no return to citizen node function, you would need 2 additional accounts if you wish to do so without assistance and relying on other people, if the return function exists, just one additional. In the former scenario, Main character would load up on loot. Have a secondary account on a far off node that will maximize your income. Have a secondary account summon primary, sell goods, buy goods that are rare in the citizenship node, have third account summon you back to your primary node. Sell, and repeat on the hour (if the cool down is an hour).
There are probably other means in how the family system can be exploited. So please do discuss so Steven and the team can get possible scenarios not thought up of just yet. Now once again this is all theoretical, if they they restrict the ability to travel, or force a prompt that all resources will be lose before teleport (keep in mind we are talking raw mats/processed goods which can be sold in auction house), this will solve that problem....Which I severely do hope is the case =P.
-Edit
Forgot to mention, this will also solve the problem of people summoning for raids after they complete one. Won't allow them to chain summon for raids if they are loot teleport restricted, 5head =P.
