I love the TANK position...however...

Gear wise, whenever you are about to go to a new dungeon, make sure to revise your gear.
- Have it repaired if needed
- Have the latest gear you can get (specially the weapon)
- Get High Quality gear preferably:
+ Synched down people will have their gear reduced to the highest ilvl Normal Quality possible for the dungeon, which is lower than a HQ piece optimized for the dungeon.
- Be relentless with your Flash.
+ Usually flashing twice should suffice, but its just an agro cushion, after 2 flashes keep it up with a Fast Blade > Riot Blade > Flash combination.
- Once you get to lvl 26 things will ease up a bit thanks to Rage of Halone, but still keep up with the Flashing.
- At lvl 40 life will get easer, but expect difficulties at lvl 50 ilvl 135 dungeons if you aren't up to date with your gear.

Cheers!!
