First post here!
Have you ever wondered which Heroic dragons are better than others? You might even have one of the most powerful dragons in the game, and not even realize its full potential!
Before I begin, here is a list of element combinations that result in loss of coverage.
Metal + War (Both effective vs Terra)
Water + War (Both effective vs Fire)
Nature + Electric (Both effective vs Water)
Fire + Ice (Both effective vs Nature)
Terra + Light (Both effective vs Electric AND Dark, possibly the worst hybrid element combination)
Fire + Metal (Both effective vs Ice)
Electric + Dark (Both effective vs Metal)
Nature + Dark (Both effective vs Light)
So what can we learn from this?
Coverage wise, the best heroic dragons offensively and defensively are:
High Tidal Dragon (Hits Fire, War, Light, Metal, Electric, Dark, Terra, and Ice)
High Nucleus Dragon (Hits Legend, Terra, Ice, Electric, Dark, Water, and Light)
High Entity Dragon (Hits Legend, Water, Light, Fire, War, Nature, and Ice)
High Star Dragon (Hits Primal, Water, Metal, Electric, Dark, Terra, and Ice)
High Purity Dragon (Hits Legend, Nature, War, Terra, Ice, Metal, and Light)
High Snow Dragon (Hits Legend, Nature, War, Water, Light, Terra, and Fire)
High Fenrir Dragon (Hits Nature, War, Legend, Terra, Fire, Water, and Metal)
High Priest Dragon (Hits Electric, Dark, Primal, Nature, War, Water, and Metal)
High Spirits Dragon and High Celestial Dragon are essentially 3-element dragons because Terra and Light literally give the same coverage
IF YOU DO NOT OWN ANY OF THE DRAGONS ON THIS LIST, OR OWN THE TWO DRAGONS I MENTIONED THAT HAD THE WORST HYBRID ELEMENT COMBINATION, DO NOT BE DISCOURAGED. EVERY HEROIC DRAGON IS BETTER THAN THE NEXT LEGENDARY DRAGON BY LEAPS AND BOUNDS.
