Armor Reduction Teams

Here's a team idea:  go for maximum armor reduction, or have as many heroes as possible benefit from extra right-click damage.  While you still need stuns and nukes, extra right-click synergy never hurts!

Pub: (dual lanes)

Stuns + Armor Reduction + Hard Carry right-click:

• Sven/Naga + Dazzle safe lane

Team Idea #3 (aggro tri)

• Slardar + Venge + Leshrac aggressive tri (push tower)

• Slardar (Armlet, AC, Heart) + Venge (w/ Medallion) + Dazzle (Mek)
• Offlane: Tidehunter (Mana boots, Blink Dagger, Support Items)
• Mid: Shadow Fiend or Templar Assassin (Urn, Desolator, Shadowblade?)
