Your guide is good but my group took out robo with no 40+ tanks, mostly clerics and one awesome runner. The funny part is we barely survived the first 5 mins of the KQ

. I think by far the most important part is the runner. The runner pulled like all the mobs and we picked off the archers and vivs and then we ALL ganged on robo at 3.50 min mark. we had amost 30 sec to spare. We used and only needed one real tank w/ one or two lower lv fighters and he was 39lv i believe. So we did it with like only 3 fighters. People tell me that's rare but it didnt seem that way when everyone works together + a Awesome runner helps tremendously.
