Its turning people off from buying it after the deal runs out. People are leaving the game because their Patron is running out and they don't think its a good deal to renew it. $4.99 IS a good deal, but put it next to $ .99 and it just doesnt have the same appeal however.
If we remove the stigma of not having Patron by starting it off at the normal cost, then it will lead to different expectations going forward - namely "wow im losing all these bonuses and ill have to pay 5x as much to renew it? ill just go to a new server and pay .99 again"
