I tried logging just to see, because my friend told me the same thing. However, it seems the lag has not improved for me, but yes they fixed the ladder issue.
I think they make the ladders more sensitive or something?
I was indeed very surprised when I tried running jump and succeded.
Hell, I was even able to ladder skip!!11 (;_; )
A very good improvement on the ladder issue indeed.
Also.. Posting on your wall.. Seems to attract [S]pedos[/S] people to my page.. o.o
