Coil was intended to be done with a static who shares the same goals - its the difficult raid-content back from ARR-days and was never meant to be done via DF.

Back then the loot was often BiS so people had an incentive on top of just wanting to raid - today Eden Savage has taken Coils place, making it more difficult to do this the intended way which is to get a group together who shares a common goal in how they want to clear it. That does include a group wanting to do it unsyched.
Sorry, but you're about 5 years late to the syched-coil-party and even back then you would have had to look for static comitted to a weekly schedulde slowly dying their way through the turns. Your "better way" would be to repeat that: Look for people who are intrested in doing Coil synched, agree on a date and time, read up guides or decide to go in blind - and dont expect to get every clear straight away.
