I believe, somewhere along the line, the PTS server should be handled a little better. I truly think a lot goes unheard during the PTS phase from players looking to exploit what they can during this phase and have it go unreported in order to get a leg up. There are bugs that get reported during the PTS phase, but what comes of it. More than a couple of times have I seen reports of specific bugs prior to release, which don't even get fixed. What is the PTS for? As a community of players, more need to be involved with the testing phase in order to guide the game to where it needs to be. So many complaints come from people, who could have contributed to the overall well being and status of ESO. Of course, we aren't going to find every single thing, but take the time and play on the test server and report. Hopefully, it won't fall to deaf ears and a resolution is found prior to official DLC release.
To those that take advantage of exploits continuously; stay hidden, stay very hidden. (Quakecon 1997, player caught using wall exploits, raged on by other players and desktop was thrown outside and kicked out) Karma returns in some form or fashion.
