Where to charm as a 45 druid?

[Estu]

I decided to pick up my druid after a long hiatus and I figured I'd try charming Kedge. However, I'm too high for first floor (mostly green) and I think I'm too low for second floor. So far I've had to gate once and I've died three times, and have gotten zero kills. Here how it's gone for me:

1) Get some buffs up
2) Go IVA
3) Go into the west room. Other rooms have passages to other floors (had a problem with this where a mob on another floor was CHing a mob I was fighting) or have two spawns passing through them; west room just has the hammerhead.
4) Try to charm the hammerhead. This goes wrong a lot. There's not a lot of room, so if I just straight-up try to charm it, it aggroes and interrupts me. If I root it, it takes me a while to swim to a spot where it can't reach me (meanwhile I take damage), then root breaks early and I have to reroot, reswim, etc. I end up getting killed trying to gate out.

I've also gotten crit resists lulling that have pulled the entire floor.

So I suspect that I'm a bit low for here, but I'd still like to charm. Any good areas to do this in? At what level would you suggest going back to second floor Kedge (or should I do Kedge right now, but am doing it wrong)? People have told me to go quad but quadding spots tend to be overcamped and quadding is less fun (also less efficient without a lumi staff).
