Guild Wars 2

Dailies are a fun way to level and help players have extra incentive to do certain tasks.
However, because dailies are shared, you can only do it on one character and have no control over when you have to do it.

This means that players who specifically want to use them on one character must switch to that character once dailies reset.
Additionally, some players play together and use dailies to level up with each other, using dailies as the meter for play or simply to help level up their characters faster.
That means when dailies reset, players are forced to stop playing until their friend/s arrives.

To avoid this problem, daily achievement progress should have the ability to be halted. This way, you can continue to do what you want on the character you currently playing, saving dailies for another character or for when you want to play with a friend. The dailies still reset once a day like normal, this idea is just to halt daily progress so you can continue what you’re doing as well as allow you to complete them on a different character later that day or complete them with a player.
