Well, the last I inquired about this was that we were not to use Tombola items as prizes. They will remain exclusive for the time being. This is mainly the reason why we have not yet placed them as lotto prizes. And I tend to agree too, as Elmyr pointed out, some players have pumped a large amount of funds into the game to obtain the tombola items. It would seem a little unfair to them that players can now obtain them a different way without having to spend RL cash.
However, I do not see this staying like this for much longer. Soon we should be able to use them as prizes. Presumably, there will be a Xmas tombola at the end of this year again, perhaps the old items will become available again, or new items sets being created to suit our ever evolving game. Either way, I always liked changed.
Regarding the DoI, this is a no go at the moment. The only reason why we had a DoI up for grabs a few weeks back was because I offered the one I purchased as a prize. That specific week we launched an advertising campaign along with the lotto and wanted to provide exclusive prizes in the draw.
