ok, i got it, thank you very much again for your detailed reply. You're right, i was thinking about Sweep from the solo perspective and not in relation to dungeon bosses.
I am also thinking about the HT duration increase at lvl40, i guess the rotation will go to something like: HT-ID-DIS-PH-TT-VT-FT and repeat or it should be different because i still don't have CT?
