With 14 slots, you could try 6 Defense rating, 6 Absorption Rating, & 2 Endurance, since Shield Chance is much easier to boost with mods & skill tree perks than its ability to absorb. But even then, you may want to just do STR Augs instead of Endurance. You get more damage, which helps generate threat as a Tank, & they still give you +20 Endurance each.

actually this is what i did, I put in all might augs, so my damage dealt certainly increased, i'd be interested to know if the additional damage done off sets any defense deficits.
