Need help deciding bear config

Hi, I am a level 48 bear - mostly casual gamer - just drop in for an hour of hack n' slash every now and again. I join existing games and try to always follow them through to the end (unless battery dies LOL). So I try to "do my bit" and be useful.

I want some advice on the best config. I have tried three combos recently pure strength, dex+strength and pure dex. Some Extra Int, Str and Dex comes from gear. Stats are below:

STRENGTH
*********
STR: 238
DEX:19
INT:25
HIT:88%
Crit:16
Dodge: 8
Health: 744
Regen: 13
Mana: 412
Regen: 9
Damage: 124-144
DPS: 74
Armour:93

STRENGTH+DEX
**************
STR: 165
DEX:79
INT:32
HIT:97%
Crit:16
Dodge: 7
Health: 682
Regen: 13
Mana: 416
Regen: 9
Damage: 97-110
DPS: 61
Armour:89

DEX
***

STR: 31
DEX:230
INT:16
HIT:111%
Crit:18
Dodge: 12
Health: 616
Regen: 7
Mana: 412
Regen: 4
Damage: 103 -106
DPS: 131
Armour:81

My feeling at the moment is that the dex build with additional dodge seems to be just as useful at tanking as the strength build. As long as I chug the occasional health pot + the additional dodge seems useful. I have iron blood, hell scream, crippling and super mega slash, becon, stomp, rage, evade, health maxed out with a couple of points in crushing blow. The weapon for dex is a stiletto and I think the attacks with that stack somehow - anyone know for sure?

Sorry if some of the questions above are n00b level. I have read a few threads on mixed builds, tank builds etc and am still not decided.

All advice appreciated :-)

Thanks!!
