I've been wanting a feature like the Menagerie since the game came out. This is some good timing for me too, since I just started playing with some pet builds again.
Re: 4th year anniversary I like the idea of more storage (never seem to have enough in any game) and the Battle Isle changes.
I agree though that it is hard to log in these days. My tiger in PWI is up to level 43 now and finally has new quests to rip through. Level 42 (good band if you remember them) only had 1 quest so a lot of random killing and roaming the countryside looking for people in trouble.
