My first toon ever that I got to 50 and then 55 was my PT tank but I never felt safe tanking OPs due to how little I knew about stats or the content. I learned alot about where my stat values should be at from lurking on the forums but I'm still not sure. Long story short I wonder if it would be a good idea to run with around 20% defence, 40% shield and 40% absorb in full 66's for 55 content?
