Capping resists is a great thing. Maybe this will stop all the players complaining about how easy the game is after they intentionally stack resists to make everything heal themselves to full health+use leech/comeback kid for 100% invulnerability.
I might even look at taking leech now that it isn't gamebreakingly broken. But it's not really necessary.
@El Zoido -- I like your idea. Allow resists to reach 100% with potions, or even spells, but not otherwise.
