So Second Coil has been destroyed

[Ultimatecalibur]

Actually, there were multiple things stopping people, such as the fact that it required a pre-made party. If you didn't have a static, you were screwed, since most PF groups for SCOB were either farm parties or progression parties that required you to have made it to certain phases in the fight.

New players with no experience were left out in the cold to try to start up their own parties, most of which didn't get much attention because people with clears tended not to be interested in helping strangers get clears.

This, "Late to the Party" factor, is a major problem. I finally managed to clear T5 midway through 2.3, but few groups were willing to teach a new tank T6 which they had been already farming for close to 3+ months. You pretty much need have the most recent endgame content unlocked on the first day or you will lag far behind.
