I like the Beetle. He's so underrated. Beetles can kill the Avatar and Horned Reapers, you know?
Out of curiosity, why exactly do you hate the Warlock?
But they're so overpowered, who needs Heal when you have the second highest stats in the game? Second to only the final boss.
The reason why Horned Reapers are rated so overpowered is because of the exploit of the Temple. Set them there and they'll just pray, never get angry. The "Throw gold on them" is a glitch/exploit/design flaw (Can't remember which actually) used to avoid their massive payday. It also can be utilized to just make them happy once they get unhappy. These things cancel out the Horned Reaper's weaknesses, his management difficulty. That is why he is considered overpowered.
I actually talked about the Combat thing
here. Vampires are actually one of the easier Creatures to annoy. Especially with the flaw in the AI that will send the Vampire to the Temple automatically >.> Also, Vampires are more like secondary Researchers. They have a Research Value of 3 at base level, compared to Dragons and Warlocks that have a Research Value of 4.
Dark Mistresses are overpowered too XD
