Honestly, even with 100% in all resists besides tenebrium and earth, my tanky melee was still dying a fair bit, because the enemies can hit for a good 30% of their HP, and so not having the immunity to fire means that the battles would drag on past the point of difficulty and into a grind, because I can now only hit 2 of the enemies I am fighting without killing my tank. most battles are decided in the first rounds due to positioning and CC anyway, so capping the resists like that is just annoying. At least cap it at 100% so that we can ignore friendly fire if we work for it.
