My group and I used to struggle to push the phases quick enough on T6 until I re-specced 30 STR. We could clear it but we had to take 2 Honeys a lot of the time depending on the RNG with the Bulbs, and then stand around like lemons so we didn't then push it before the Honey was gone. Once I re-specced and started actually stance-dancing, it really helped.
Same for T7 - We were struggling to kill the first adds quick enough before the next one spawned, and my extra DPS helped push things that little bit more to get them down in time.
Now that our DPS all have better gear, it's no problem, but it definitely helped in the beginning.
I'm starting work on some Ruby/Topaz accessories now, but haven't made up my mind which way around to do them yet, as the Vitality IV and Strength IV Materia markets are all over the place at the moment.
