Cause it is not just subscription, they only want that you pay some time via Credit Card, PayPal or other non one time throw away methods. If the time comes from buying time alone are as part of a game bundle is not so important for them.
There are only two options.
Option one making gold basically worthless by letting you get so much that you have no need to farm which effectivly kills player trading.
Option two having it hard to get gold which makes it feel worthy but also week for the thought of instead just work one additional hour as it is more effective then playing the game.
oh when i heard that news i was so god damn happy.
now if you ban a bot or a gold seller or any of them that are doing something similar they will go to shadow realm for good
and since 95% of botts are from Iran and turkey and russia
the next time that they want to come back and fug the economy they have to pay with real money and since they are not in a normal country they cant do it easily with a credit card or ect due to sanctions
THIS WAS A LEGENDARY MOVE BLIZZARD I LIKED IT.
lets go on Destruction of 2x4 farming and group farming next
i really want to see them going to shadow realms too
