There’s no such thing like the best hero. Everything depends what game aspect you consider and what’s the synergy between that hero and the rest of the team.
For example, everyone loves GM and Hel. They’re awesome indeed in raids and wars but not really great against titan.
I have both of them maxed but don’t have any good green. So I’d say Zeline is one of the best HOTMs: 1) fast mana, 2) dispells buffs from all enemies, 3) I really want her
Seems pretty unanimous that Margaret is trash. I feel bad, because my girlfriend was “lucky” enough to pull one (though she doesn’t like her either).
Her special skill isn’t totally useless, but she definitely needs a boost somewhere to make her viable enough to use regularly. I don’t even have any HOTMs, but I’d actually prefer to pull another 4* hero over her.
