Like others have said Luclin was a mixed bag. As a caster, speicifically a Wizard I liked a lot of it.
Pros IMO- AAs really made certain classes shine (particiuarly Wizards and Rangers) and was a pretty cool way to advance your character.
- Ssra was an awesome zone
- The loot had a lot of really cool clickies
- Horses where a nice addition that still felt very fantasy
- Caster gear! Seriously needed after the velious expansion was so melee based
Cons IMO- VT was a terrible raiding zone
- PvP was broken in several ways. I think 2hbash was a game breaker
I think a lot of people didn't like Cats but I didnt play one and I didnt mind. A lot of people complain about spires but in truth they only went a handful of places and had a wait time. I made way more money as a Wizard TLCing people who wanted to be various locations quickly and were hanging out in the bazaar.
People seem to be getting confused, there were no instant teleportation books in Luclin. Those books came in with PoP.
