Time for Coil?

[CodeCass]

Alrighty, So after a few months of playing, my SMN is finally iLevel 90! I've got my Zenith weapon, and currently gathering Atma. I'm feeling pretty spiffy in my ST gear. But now I feel like I've kind of hit a wall. Not sure what else I need to do next. So my question is this: is it time to start looking at doing Coil?

Now at the time of this post, I've never touched Coil. It's always seemed VERY intimidating. I know nothing of it, other than evidently it's hard as hell. I have some friends that look down on it as an elitist-only activity, but I myself have no clue on the subject. All I DO know, is that I'm ready to start doing something new and working towards more end game fun!

So...at my current iLevel of 90, is it time for me to take my first step into Coil, or should I be focusing on something else?

As always, any and all help is greatly appreciated!
