ToA has been made easier. Lots of the requirements (such as being ML1 to enter ML5 dungeon, being ML3 to enter ML7 dungeon, etc.) have been removed. You can also do the trials in any order now, finally. Lots of the artifact encounters have also been tweaked to make them easier so you don't require a small zerg to assist you.
However, at least on the cluster I played on, RvR went lame. There was no more 8v8, just 3+ group zergs on a nightly basis and stealth zergs. I played on Palomides/Midgard, on the Palo/Gawaine/Bors/Merlin cluster. I quit about a month ago after over 4 years of playing.
Got Elder Scrolls IV: Oblivion and Guild Wars to keep me occupied now.
