Hey! So I've recently got into playing my shaman again in pvp. However, there's an important thing I just cant get the hang off. On what spells should I be spending UE (Unleash Elements) on in different situations? I normally just use it on Riptide's for a powerful HoT or on a healing surge if someone is in risk of dying. I also usually play Arena 2s/3s if that makes a decision on what I should be spending it on! Thank you in advance.
