Seems like you should be able to tank T2 just fine (w/o inspecting your magelo profile).
Maybe something obvious is missing?
- you dont have your defensive aa's
- visit your gm trainer to make sure you have "primed" dodge / riposte, etc
- being an SK you need your kael gloves for clicky defensive
- your cleric should be buffing your sk with Unwavering Faith for melee mitigation (rank 1 starts at 5%)
- your shaman should be buffing your sk with Talisman of Sense for melee avoidance (7%)
