I dont mind if there is a short time limit on re-entering from the point of getting burnt out or making the content get old too fast. There are a few things though tht are important. The dungeons should be fun, challenging, and give good loot that is not dropped like candy. In regards to what is bad about the 5 min time limit, I only see one that bothers me, but its a big one. With a 24hr to 72 hr time limit, you can limit how often people go in so that more groups get a chance. But with the fact that its first come first serve, and it only has a 5 min time limit on re-entering, and we know that there will be a limit on the number of groups that can simultaneously enter the instance........... this could be a huge problem. There is nothing to stop people from spamming the Instances over and over. So I have a really slow ISP and I lag all the time. Does this mean I'll never get to see the Dungeon until its popularity dies down in several months and all because I cant spam the entrance fast enough?

For clarity, I could care less about any other issue related to the quick re-entering of the dungeon with the exception of even being able to access it. Couldnt they have gone with a more resonable system? Like maybe anyone can go say 10 or 20 x a week at any point they want too (provided the instance isnt at max group capacity). That way people could still go more often than once every day or 2, and could even go a bunch of times in a row, but it wouldnt cause a never-ending bottle-neck that would always make it hard to enter due to the spamming, even though supposedly I should be able to enter every 5 mins. This is the bigger issue to me, not whether we should be able to enter that often or not.
