Im sure that everyone notice that Witch class is weaker than others. i have some suggestions to make her better.

1. Replace her poison potions with Slowness potions
Poison is useless on arena becaus undead and spiders cant be poison with makes this potions useless, slowness potions will be way better
2. Replace invisible with Lingering potion of healing
invisible have no effect at all, its just waste of place

And im pretty sure that no one is curing Zombie Villagers becaus there is no need to do this and no one know that Zombies can be cured, but why Deals are dissable?

 

It takes 5 minutes for them to be cured, it's better to just kill them first imo.
Neutral on this.

 

Neutral, as you can cure zombies but it take time and you cant trade with villagers as they can be easily be abused on selling/buying cheap stuff from them and ripping the economy off.
