This might be bad, but what I'm used to doing is save my opener until after the first stasis. The reason behind this is because I use my b4b twice during the adds. I pop it to pad on all the small adds and I pop it when it comes back up on the physical add. It'll be down when Alexander returns after Divine Judgement, so what I do is just do my normal rotation without any buffs except botd. I also use a Jump here after my first 4th combo. With around 645SS I'm always on my second 4th combo when I have to go into position. So this fits well. What I do then is I jump back on the boss with spineshatter and use my opener after my HT which will be the second GCD I do on the boss. This also lines up with hypercharge pretty decently because my mch uses it on cooldown at the start so it's normally up after the first stasis. I get decent numbers with this and I want to hear other people's opinion of this.
