If you had read the first post, you would know why v5 is an option.
I did read the first post but there is no reason to use v5 when it isnt ready, we have waited this long. Lets just wait until it is 100% ready before using it.
v5 has been in the works for a loooooooong time, and frankly I think it would be a much longer time before it is fully implemented if we were to wait for it to be perfect. I doubt it will ever be 100% ready, because there will always be small bugs and new addons that will be found.
On the other hand, I don't think it is ready at this point, but that's just based on what I've seen from the /1337v5 preview site. I'm sure a lot of the missing stuff on there is already done.
No I mean, when it is ready to be used, if it is ready now, then use it, but from what I have heard that it is not ready yet, when I go on there it brings me to the file not found page or access is not alowed, lets fix all of those first!
