EverQuest: Call of the Forsaken.
 

Does anyone have any thoughts on EverQuest's 20th expansion?

Here's some minor information on it: https://www.everquest.com/expansion-content

Looks like they have taken, err I mean created, some inventory code for mercs like the bot inventory used by emu for some time now.

Yes, they created a special tab in the inventory that shows the helmet, chest, primary, and secondary of your mercenary. The have also created a mercenary-specific AA tree with the added benefit of differentiating between which type of mercenary uses which AA. They have come quite far since I last played, and it's fantastic.

I was in beta and played it on test prior to release and as far as I am concerned it sucks major dick.
