Do you have to buy into the game to gain XP after 65. I've been doing every Vanguard quest, dungeon, mission, killing ten of this and ten of that and I have gotten zero XP the bar hasn't moved. I kinda was ready to give up yesterday but today again I did my dungeons, arena champions things, vanguard quests and missions plus the Isle of Dawn kill ten of this ten of that endlessly and there has been no reward with XP.
So how do you earn XP in the game cus I'm getting absolutely none from what I am doing at the moment. Seems really pointless to me.
