There needs to be some way to reach at least 100% resist just because there are so many spells and talents that rely on standing in the middle of damaging terrain. It's not just Zombie, it's also Elemental Affinity, Explode, Storm, Self-Immolation, so on and so forth.

I get nerfing the interaction of Leech and Comeback Kid, but broadly capping all resists at 80% is a huge design change that breaks a lot of skills and a lot of builds.
