@EleNiggle - we were doing t6 for a while and had a sudden jump from 2 refreshes to 1 refresh. a combination of us gearing and starring up more toons, and getting a better idea of both individual and guild strategy for the raid.
we had a well thought out guild strategy for the tier 7 and made sure everyone stuck with it. the most recent tier 7 that we just completed was a breeze, and was much easier and quicker than a tier 6. the rancor is tougher at tier 7, particularly in phase 4, but he has much less health. so if you have enough 7* toons and don't waste them across the guild (where the planning and strategy comes in) then it is straightforward enough.
The rewards are incomparable to tier 6. In a tier 6 raid we might get one or two complete items between 50 of us. In our last two tier 7s we must have got about 20-30 complete items between us. It is probably 10 times higher drop rate for full items. And finishing 50th in tier 7 guarantees at least 15 unobtainable parts. Credits and guild currency are higher as well. Top 5 in tier 6 is probably equivalent to bottom 40-50 in tier 7 - so for the guild it is unquestionably better to do tier 7s if at all possible.
The only practical difficulty is that now our guild knows what to do, we can finish too quickly and we have to make sure everyone can get in an attack before it finishes!
