this discussion was there several months ago. several people argued that those with multiple accounts(i.e the same guy/girl who makes 2 supermech accounts with different email ids) will trade all their strong weapons /items into one account and become extremely powerful.
i also had given a solution for this : namely the old barter system-where an epic item gets exchanged for an epic item, legendary for legendary and so on ; so that one can’t have all his/hers strong weapons poured into one account as something has to be exchanged. well this is not going to happen any soon;
i know that this kind of discussion was there before i took part in it and nothing has happened till now. hope someone may one day convince ts about this.
they might do it if they can get commission-profit by acting as mediator for the trade.
