Dual-wield sword Barbarian strategy?

[Tuy]

I agree with everything Kandrathe said so I'm not going to repeat it. I haven't played Classic Diablo 2 since LoD came out, so I can't really remember anything about it. This is just based on LoD experiences. Two Barbs that I made were a Whirly/Zerk Barb and a Frenzy Barb, which I'll tell you about.

My Whirlwind Zerk Barb would use Berserk on monsters until his life orbs would get low then he would use Whirlwind to refill his Life and Mana orbs. Whirlwind is a good skill to invest in because although the damage starts out negative, it gets higher until it gets into the positives. The advantage with this build as opposed to just using Whirlwind on everything is because you can effectively tank for ranged characters. I'm not sure if this is what you want to do since you seem very interested in the defensive skills, and Berserk lowers your defense to zero.

You also seem interested in Frenzy. I've made a Frenzy Mace barb who is very effective. Frenzy isn't exactly like Double Swing. It doesn't have that dramatic increase in attack speed initially, but as you put points in Frenzy the attack speed will increase with every hit until it's as fast as Double Swing or faster. (I'm not sure how much Double Swing increases your attack speed. It may be 50% or 100% I think.)

Also, I'm not sure how good Battle Orders is in Classic Diablo 2, but it may be worth investing in. Also taunt is a good single point skill to lure those ranged attackers to you.

I hope this helps. :D
