I think that they just did not support old version so they would not want to give effort to introduce "pay money for official items" in old version.
For the new one, I guess that as they paid some money in order to have the official items in game, they wont to avoid get nothing from it from tanking tokens.
Tanking tokens is not as difficuld as previously.
Asso tokens, daily bonus tokens, sponsor tokens, negotiation tokens are some ingame token incomes that can make you a forever free player.
We do not want that, do we, nordeus?
