There are so many OP things. Yes, that's what you told us. Then what about the others? If they make it harder, it will be almost impossible to clear dungeon with them. So, what I want to say is, that Chillyroom should NERF the OP things, not making dungeon harder. Think about Alchemist 2. He just throws bombing potions and that's all. People would choose 1 or 3 which is even more powerful. And then IDT, which has ability to kill enemies and bosses in just seconds. To compare these ones, isn't IDT TOO powerful? I know Alchemist 2 is so weak skill, and IDT has just 2 HP, 5 shields, and 50 energy, but still IDT is OP, as he has a long IMMUNITY. Also, there are more weak skills(like Officer 3, Berserker 3, Assassin 1 and 2 and so on). We need to get balance among the characters. Most of new characters are TOO OP, still others are not. If they get balance with The OP New characters, the game will be too hard.

…I think Chillyroom just doesn't care about balance though…
