Trying to do the Math: AC vs. -DFE?

[lyyn]

But in most actual play session, most rogues I played did not always have enough arrow damage to stun at clvl 30 either. There was a few exception. One rogue I had was low ac, resist shirt and hat. +Damage bow, and all her jewelry slot was +All. Iirc Her DEX at the time was high, but not maxed.

Yep, my situation exacly.
Well, I guess I have to get used to having my inventory open and swaping gear a lot. At least until I pumped some more iron.
Thanks for nudging me in the right direction.

BTW, I forgot to ask :

IMO Holy Defender > Stormshield

?
kind of goes back to the original question. So you didn't feel 25 AC is worth +4 (+6) DFE ?
