Anc mvn help

Just got mvn to ancestral. Have anc dw cooldown, gt cooldown, and spotlight angle. Been using 8m bh but just rolled anc gt duration. I know that's really good later but I don't have gt+ and won't for a while. Currently gt is 45 seconds and bh is 33. Don't have perma bh yet. Keep the gt duration? I was hoping for dw quantity.
