Um, I guess you can use it 7x a week instead of once a day, so if you burn through seven bonuses in one day, you have to wait a week to use it again?

Since I don't normally instance or raid, I have no idea why they thought this change necessary.

Now: You have to log on every day for an heroic to get the additional reward.

Then: You can do multiple heroics a day. You get the additional reward for the first seven heroics you complete in a week, regardless of day.

It's hailed by people who can't log in everyday and / or do not have the time / inclinination to run an instance everyday.

This change is for me. I play on the weekends these days, if AT ALL. That means I can do two daily heroics, tops, one Saturday and one Sunday. This way, if I log in and do three heroics on Saturday, and 4 on Sunday, I will get Valor points fro completing each one. If I fit in an eighth, that will just be a random dungeon run, no valor points. See? It's for folks woh DON'T or CAN'T log in every day, so they can still have points, especially like me, during a raiding hiatus. :)

+1 for what Iano said. I have a strange work schedule, in which about half the time I work is overnight. During the day, I either sleep or take care of my one year old son. Finding the time to log in everyday, wait 30 minutes plus for a queue, then another hour to actually run the instance has made it nearly impossible for me to have any kind of pve activity.

However, chaining several heroics overnight, when I have to stay up late in order to prepare myself for going to the night shift, is much easier. This is a very welcome change. I'll finally be able to get raid-ready.

Ah, that does make sense. Thanks for the explanation.

I wonder if this will apply to holiday dungeons.

I'm thinking that it is unlikely to apply to holiday instances. Or if it does when first applied, it may not for long. I think it likely that people queueing the first day of the holiday turning on and then not at all for the rest of the holiday week could be pretty severe.
