I have 5 Rakata ^^ me and my guild do Ops twice a week and I already said they are good.
I have the Dacrons which actually provide me with benefit.
I've done all the ops on normal, hard and 7/10 Nightmare mode we are raiding tonight to try and get 10/10. The Hard mode Flashpoints are pointless, they take way too much time, are too easy and don't provide a better award than operations, and btw you don't need to do Hard mode flashpoints before doing Operations.(our entire guild have geared up from just doing operations twice a week and pvping)
Yes we have a very active guild, I've never logged in and seen less than 10 people online and our guild even have 10+ people join because they were "fanboys" of our guild killing them over and over in warzones.
I don't want a pink crystal and plus I've never even heard of it T.T
Yes, killed all world bosses except the latest one they just recently added.
