Extreme Primals are easier content than Coil ~ They are designed for ilvl 60, 67, 70. Coil is designed for level 80.

The thing about this strategy - is it's not about not having the skill to do it. It's about being able to PUG it without taking 6 hours. PUGs are bad. Terribad.
I clear turn 1 through 5 on my main in an hour and a half on good nights. (Occasionally someone, or myself has a bad internet night)

On my alt though, which has relic+1, full darksteel triple/penta melds, I struggle to clear it because I go with pugs. You can explain the strat 500 times, you can walk people through it, show diagrams, show pictures, videos, explain in depth, let people ask questions, run several practice runs, but at the end of the day your paladin and bard will still forget to silence and your dragoon will stand still with allagan rot.

You are dependent on other players ability to listen, and that's a hindrance in pickup groups. And no I don't want a static for my alt.
