Based on Block and Aggro tanking with some Healing for when is needed, also good Aggro pull and CC to gather enemies and get them closer to you, and as recover mana when get damaged with low cost combat skills only need to keep an eye for when heals are needed and dont get out of mana while keep fighting.
Also good quantity of combos to do by yourself and boost your skills without need more ppl.
Feel free to ask any questions.
