Played as "In Nomine Dei Nostri"-Warden Tank at EU Server under lvl50.
I used 5x Orgnum Scales , 5x Beekeepers Scale, 2 Vampires Kiss.
nearly 4k Healthregen, under 60% life +50% Healthreg so you have something around 6k lifereg every 2 seconds. If you become a healthreg-debuff of 30% Orgnums compensate it then too.

Its perfect to irritate enemies. Run as fronttarget into enemies, outposts and keeps. Easy to handle 5-10 (normal) enemies at the same time.
Use Growing Swarm - Gripping Shards - Arctic Blast (some time caltrops or magicka detonation) with Ultimate Permafrost to rush into masses of enemies.

Only problem is, you made really low damage, but after a while I realised its totally easy to compensate with coldharbour balistas. Therefore you run in fight and set up some balistas (protect these with AoE Ice / Caltrops) and stand in front of these weapons to shoot at your own position. I had no problem to pull all guards of Outposts, Ressources or Guards inside Keeps and kill them with AoE Firebalistas.
