I have to think they remove the limit on it. I thought they might do that once they got the rest of the content in, but they didnt. Maybe they thought it was better to wait so it didnt look 'obvious'.
But Hytbold was basically the way they gave 'content' for people to do on a daily basis to fill the gap between release of RoR and the time when the instances came out. Most open world and deed quests were done in less than a week by a majority of the people. So rather than have everyone just leave like they always do they gave them a 6 week grind, that if nothing else enticed them to log into the game at least for a few minutes a day to complete. They did tie it into the reputation grind which was obvious but it still was gated by a 5 turn in per day limit.
