As much as I understand your concerns for the Black market and those selling accounts for certain exclusive account bound items such as these pvp tourney shields and humania face accounts.

I have to agree with the others.

Having the opportunity to achieve certain items on game due to winning a pvp tournament, capping fast, winning a competition etc, be proud of it. Keep your reward.

Not everyone on game should be given the choice to merch or trade these items earned by those who achieved these milestones.

Let those who earned it keep it and let it be exclusive to them.
