Yeah but these guys were pro and have like +9 items + you need to use pots all the time. I have plenty of cash items pots and even with them it was risky.. I've done 4 tmq with them & all was success, we had 10 min times but on other hand I died 3 times & some of them too.
Without high dps & overall experience I'll strongly advice against that kind of teams unless you have 2 or 3x Ultimate Majin in party. Later with healer I got similar time and it was more cool cuz I could go Kaio x2 & I don't used that much pots. So yeah it can be done without healer but only if you sure you and your team can do it. Otherwise it is suicide.
