@Koll I say this because for example for me there is nothing atm to make me spin that wheel even tho there is othel 7, enchants witch are really good for some beginer, but i don't think too many old players will get excited about this, but if you put a unique accesory (ofc don't put jetbikes and wyvern and big mounts to make server look like after an allyen attack) especially if you put warrior's helmet I will spin that wheel for 10 euro each mby even for 10 times to get that.
Also I'd say adding lvl 3 epics ( mby except, zaken it's still to few of them on server to put them in events, even if they are not permanent) with 5 days duration and mby 1 time a month limited per character, so this way they can be used only 2 days in oly in same weekend , they will be still worth it but won't have a major impact
