I can only recommend that if your character has no medidation skill, remove mage armor from your pieces or make armor from plate and dragon armor.
I have a tamer with no meditation skill. She only has magery for gating. I removed her leather armor and build a suit in a combination of Dragon,Plate and Ring armor. I using refinements to give it all 75 resist. And i'm very happy with the results. Now when she gets hit , all her dex is not gone and she still be able to run. Helps for taming big things too .
