I also want to just give a little tip :

In ShB they increased the time it takes for your combos to fall off. Which means that you can now start your Souleater combo, go into your Delirium window, spam your Bloodspillers, and then continue your Souleater combo. I've done it plenty of times now since too much skillspeed makes Delirium come back right after Hard Slash instead of at the end of the previous Souleater GCD. With the old shorter combo delay you'd have to either delay your Delirium until the end of the combo you just started, have a Bloodspiller ready, or delay your GCD, the last one negating the benefit of having all that skillspeed. Now you can just do Hard Slash -> Delirium -> BSx5 -> Syphon Strike -> SE. It also works with WAR's Inner Release and GNB's Gnashing Fang combo.
