Bounty can now be gained on people defending a target - it is calculated off of the TARGET'S bounty level (not the defender's bounty level), and is half the target's bounty rate applied to all defending troops (so a green title defending a red title... there is half the red title's bounty available on all the green title's defending troops, for example).
I've put the key bit in boldNow, if you have adrenaline rushed a -1 ETA mob to your target, after all the bounty calculations are done (based on the usual bounty guild requirements), your bounty is doubled. If you had a -2 ETA mob on your target (so you were REALLY feeling crazy), you will get 2.5* whatever the bounty would have normally been.
The adrenaline rush thing is a bit overpowred as it is.
