D3 skill restrictions in D2

If Diablo 2 had the same skill restrictions D3 has (6 active, 3 passive), what builds can you come up with?

I'll start today by introducing the barbarian, one of several classes I can play in Diablo 2.

Active

Frenzy (dmg)

Berzerk (dmg)

Battle Orders (buff)

Leap Attack (dmg/movement)

War Cry (CC)

Whirlwind (dmg/movement)

Passive

Natural Resistance (def)

Sword Mastery (att)

Iron Skin (def)|||i dunno what to say for DH actives since it's a new class in D3 but passives i can definitely say

Resourcefulness (regen)

Killing Spree (increased crit chance after killing something)

Back to Basics (increased weapon dmg by 100%) in the early stages and then switch around with Aggression (increased attacks by 20%) or Weak Spot ( increased crit dmg by 100%). Weak Spot is probably going to be my endgame passive since better items will give more crit.|||Can I assume the skills also scale with lvls? If so:

Active

Inferno

Nova

Hydra

Frost Nova

Teleport

Frost Armor

Passive (the Sorc only had 4 so...)

Warmth

Fire Mastery

Lightning Mastery
