When you initiate, use Butcher's Block Combo to build up some enmity first. If you start with Storm's Eye combo, there's risk that you'll be taken aggro by PLDsubtank or geared DPS.
then use SE combo to keep buff up and use BB to build enmity when you have buff. If you see your enmity is much more than your team, you can throw some Storm's Path :P

also learn to combine your skills together for better performance and learn timing to use Inner Beast.
