Sorry I'm still a little confused. At one point, they mentioned addressing the directional requirements because there were some instances were it was impossible to get behind the mob to start the combo. Then they mentioned at another point that they didn't want to change positional stuff because it was affect current rotations and gameplay.
I like the Heavy Thrust buff change because the mob can be slow to turn on initial engagement, but the help text doesn't really get into how you still need to be to the flank for the Ring of Thorns combo.
But I am still confused on the Chaos Thrust combo because I can apply the DoT from flank and behind. It is supposed to both, or one position is supposed to have a greater potency than the other?
