I've noticed that with this patch's dragoon change, it is possible to do a 4th geirskogul in 1 BOTD. Problem is, you delay your BOTD refresh by about 10 seconds, so it is about 4 geirskoguls per 70 seconds. Another thing I've noticed is that you can't do 2 geirskoguls + B4B if you did 4 geirskoguls per 70 seconds. Is it worth doing 4 geirskoguls? You only have about 1 second to do a 4th attack, and that's if you are always attacking the boss. I did this small test with 2.39 GCD, or 634 skillspeed.
