I remember reading a post awhile back saying Guild Achievements will give big chunks of XP and will feel really awesome as you complete them.

My question is this:

With guild XP per day being capped at a certain point (I think 624,000 currently) how will this effect completing guild achievements? Should people not complete them when the cap is already reached because it would just be a waste and not count or would it rollover to the next day?

Or maybe I am misunderstanding how the whole process works or will works.
