I form a lot of groups and acquuired GoD on pre-release, as such I have been accruing some leadership AAs.
20% of your experience sinks into leadership AA's but only if you select it. Like AAxp it can be turned off.
Pressing 'L' shows the leadership window.
I am about to ding 5 leadership AAs. For my first 3 I saved for the 'Mark target' AA. This is a very nice AA. Put simply, as group leader you can select and mark any mob with a large, bright yellow circle. It is therefore obvious to all in the group which they should be attacking and also to the enchanters etc which should be getting mezzed. Myself and a chanter friend (who has also ground the leader AAs) love this ability and so it seems do those we group with.
When I ding 5Laas I plan to train the mark mob health. An amusing AA I have seen it puts the mobs health percentage as a glowing figure above its head
Thats useful? Well not really but it does look very nice and that is what is important!
