While the icons etc have been fixed, the new addresses cause extra work for mods and those who maintain FAQs.
It is harder to navigate.
It is not as easy to maintain links. Previously I could copy and paste into a post an address from the address bar and just edit the forum number, thread number, or post number. This no longer works.
Sometimes when editing a post I am thrown back to the first page of the thread instead of remaining on the page I was on.
The net effect is it is harder to work on the stuff I work on. Together with search problems that still aren't fixed after so many months, I sometimes wonder why I bother trying to be helpful.
