Always thought it was a bug. Bullroarer release notes say it is out of here:
Some captain specifics in these changes, which are of course preliminary as they are on Bullroarer:
- Set bonuses that reduce Defeat Event Cooldowns no longer stack. This will prevent unintentional stacking that could reduce cooldowns to 0s.
- The Captain's Cloak of the Fornost Captain and Wyrmfire Mender's Ring have new proc effects on them. These proc effects are set up to trigger off the Captain's healing skills (and ONLY the Captain's).
And a mounted nerf, alas:
Reducing damage done by Cry Wrath, Cry Havoc and Rally the Riders by 10-15%. Sorry to do it, but Captain damage output was far too high. Even with the reduction they are still capable of massive DPS while mounted.
And a nice one:
The Recovered and Unearthed Iron Shield now give Might in place of Will, as they drop and are intended for Captains.
