I love our elite skills too. They’re ok. Since you’re able to move with renewed focus, you can support your group/other players very well. Also the tomes are nice. I don’t get all the people, who call out for “overpowering elite skill” – it’s a bit pathetic, imho. Read, learn and play the skills you have. If you want stability for the 5th tome skill, then use hallowed ground. I’d say that these three elite skills are enough powerful for the guardian, who already is a powerful friend/enemy, hrhr
