Level 16 Druid Need Advice

[Malinkadink]

So 1-16 was pretty easy, i went to EC to level with friends early on with my halfling, then from 6-16 i was in and around the crushbone area and i have to attribute the pads and belts for a few of my levels which was awesome. Now that i've outleveled crushbone im not sure what i should do. I went over to east karana to try to do charm killing but my charms break randomly and its not very efficient at my level, maybe im doing something wrong?

The only method thats working for me is root/rot but since my root is only about 36 seconds long and it usually takes me 90 seconds to kill a mob i go through a lot of mana and can only really kill blues since whites and yellows break root way too fast.

I checked Oasis as well by the crocs and there i was actually able to easily charm kill caimans but its so populated there with people so not enough mobs for me really.

Should i just try grouping?
