Frequently Asked Questions (FAQs)
Subjectively, Commandio and Fire Deliver are two of the best units due to their scaling and synergy with most team comps. Blood Samurai and Yellow Dagger also shine in DPS ineups.
Not necessarily. If you're running high DPS or Burst snipers, you can sometimes get away with no tank. But for Boss fights and late game, having at least one tank like Green Beret or Red Heart helps a lot.
Only early on. Most Hero-tier units fall off fast, and you should replace them when you unlock Ancient or Legendary Mechanics. They’re mainly filler for the early stages.
