I feel like daily tasks and bounties are too specific. It forces you to stop what you're doing to focus on them or not do them at all. Simple ones already exist, like selling 23.6m gold worth of light armor for tasks and surcharge/discount activities for bounties. They should all be reworked towards that end or possibly even more simple.
Examples
Bounty: Run 3 quests
Task: Sell 15 weapons
