Removing pet hunt is a bit silly. It was very useful for weak pet prof characters, and a must have for solo missions for froob pet profs
After like 5 minutes pets go out of range anyway, or reset to their default state likely training and killing the owner. Not really eula breaking
Removing auto attack is a good idea tho.
While it would make certain sense to make the game require more attention, in my opinion the biggest merit of AO was for me that I could play mind numbing things like inf missions while chatting on MSN or browsing the web
next monster, Q, spec attacks, perks, back to browsing then repeat
