This is my first time contributing. Anyhow, for those high end arena shamans that get Call of Elements against melee cleave, there is this small exploit:
1. If you drop totems that qualify for the Call of Elements reset, such as healing stream/ earthgrab, earthbind/ grounding, etc. You can reset their cool down and use them again.
2. The exploit comes when you use these totems, get pummeled/mindfrozen/rebuked/ or anything that qualifies as a hard counter, then you use Call of Elements to reset their cooldown and can actually cast your totems while being hard countered. Usually, if you get pummeled, you are locked out of your nature spells, and cannot cast any totems.
Example: I'm getting trained by a warrior and rogue, put down earth grab and healing stream totem, try and cast a heal but get pummeled, then use Call of Elements while pummeled to put down another healing stream totem and another earth grab totem. My life is easily prolonged for another minute or so.
If anyone has a question as to how to do this, let me know and I'll try to explain it better. Enjoy!
