<t>Hello. Im using Beastmaster Maxdps. Its working great. But one problem. There seems to be a slight (0.2 seconds) delay between abilities. <br/>
This is giving me about a 10% dps loss i certain situations. Anyone know a fix?<br/>
<br/>
Checking the combat log, I always get a spellcasting fail ...
