The patch 6.1 PTR introduces a number of updates to the garrison mission table UI, many of which will be well-appreciated. First, the mission table provides more at-a-glance information about mission rewards without need for a mouseover: ilevel of equipment, the exact number of experience points, and so on. If you do hover your mouse over a mission, a new array of information will be displayed: the ability counters required (and whether you have followers who can counter them) and the mission availability -- that is, how long the mission will stay in your list before it expires. If you have a follower who could counter something but is currently unavailable due to being on another mission, the tooltip will even tell you how long until that follower becomes available. If a mission will expire before that follower returns home, you can quickly and easily make the decision to try that mission with less than 100% chance of success.
The tab which displays your list of followers has also been updated. At the top of the menu, the UI now displays the total number of each ability in your active roster. If you have 7 followers who can counter Powerful Spell, for example, that is displayed at-a-glance. As someone who keeps a spreadsheet of his followers, it's a welcome addition. It's likely I'll still keep my spreadsheet, but having the ability to quickly reference that breakdown will make it easier when it comes to recruiting new followers from the inn each week. Using follower upgrade items has also changed: you no longer click on the item, then click on the character's portrait in the list. Instead, you click the item, click the portrait in the list, and then click on their full-size image to use the item. That change seems unusual -- it adds a redundant step to the process -- but the redundancy might be intended to prevent misclicks.
