This technique does not seem very common amongst pk, i have tried it , if done properly it is more effective than minor combo, the problem iss it requires more concentration and difficulty, however it looks like the aternative to mh combo is either hp pot, or minor +hp pot.
So post your technique, back in the day when i tried it this was mine
I am used to using 67 for minor and soul pot for 8 so i figure keeping with the basic configuration with help keep familiarity.
im used to dual minor so i may go 67 minor 8 soul and 5 hp pot as that will be most familiar, but leaves less room for attacks.
basically all it will take is practice for me and sme getting used to.
i dont really see the cooldown as a disadvantage as this method is supperior when done correctly any way.
