Shaman Wearing Druid Gear?

[scooter]

Shamans are imo - the most versatile class.
there are many wrong ways to play them but through all my adventures there isn't a single correct way to play them either.
If you are more reliant on grouping, worry more about your mana. If you like soloing, worry about HP/AC. Shamans can strategically cast spells in a group and never take a hit, or you can be super aggressive and take hits all the time.
Soloing can tank and melee, or root and rot.
the list goes on.
the point is - try out what works for you and what you enjoy the most.
