I think the resistance cap is a good thing and is more in line with other games. The 100% resistance made things too easy and the healing at over 100% made no sense at all.
I would respectfully disagree with >100% resist not making sense. It actually makes perfect sense mathematically (damage - resist*damage = hp change), and thematically - a zombie is healed by poison, so why should a zombie character not also be healed by poison? A fire elemental is healed by fire, so why should an extraordinarily fire-resistant character not also be healed by fire.
If the game is too easy, then make it harder by challenging yourself. Don't give yourself greater than 100% resist in everything. I don't understand the point in balancing a single-player/co-op game as if it were a PvP game. This change stifles creative builds and ruins the fun for a lot of players.
Not saying your opinion is invalid - just that I disagree with it.
