My barb is a secondary character that I do not play a whole lot since Epic destinies came out.

He is just too squishy so I am looking for anything I can do to improve his survivability.

Here is his current build

Was wearing Dragontouched robes with damage guards but he would just get destroyed. Currently wearing epic calvary plate.

Currently a level 21 Half-orc THF barb

Any advice would be helpful. He used to be fun to play, not any more. Not since the changes to AC.
