So no one has to stsnd in the aoe to get the buff?
You and your group members in the circle gain Major Courage for 20 seconds
ground AOEs proc it
6 people in a group get the buff per second, so over 2 seconds everyone in group can get the buff
olo aoe lasts for 5* seconds, buff lasts for 20 seconds.
in theory it's better than Spell Power Cure's major courage sourcing, which requires overheals and only lasts 5 seconds
in practice you have people standing off in the corner heavy attacking and rationalizing that they don't need buffs/heals if they aren't taking damage while trying to get their cats to stop chewing on their computer cables
