But I believe that it doesn't make any sense, since there are not even any transclasses on the server.
The promise of a server without Pay to win goes further and further with this. This puts a much higher advantage on those who pay. (What's the use of making a C.MAIL 99 HDEF, if you just pay and get 200 + HDEF (assumptio)?
If the Staff wants to continue with the scrolls (of a class that doesn't even exist yet), that is only allowed in pvm environments, and in pvp it is disabled. If not, you can believe that you will lose more and more players.
Note: I tested using dispell, and it is not possible to remove this assumption.
