THis would be extremely helpful... a little blurb after first logon after a patch that says things that are very game play changing... you don't need to list everything in the patch notes... but really important things would be nice to have a heads up about.
For example..
Your key bindings have been reset. Would have nice to get heads up on this instead of wandering into a mob and finding out the hard way. And this wasn't even in patch notes either.
Option to reset points for free or at a discount should be told up front too without pouring through patch notes. I would think that if someone missed an opportunity to do this simply because they didn't read every patch note... that would not be a happy camper!
I got a single pop up about some crafting points being reset, but it was so fast I couldn't read it. That was nice, but there should be other priority notifications given too I think.
