What shields are you using, Sandy? I'd struggle with the lack of mobility from heavy armour and shield with only 6 aths. I can't bring myself to use any shielder build with less than 8 aths, but I tend to run around doing my own thing rather than helping my team, he he he.
My current build, using a soon to be +3 heavy heater shield:
lvl 37 21/24
7PS, 5 IF, 4 shield, 8aths, 8WM
Can take a few hits, do good damage and still have good mobility with 69 body armour
