-In Penguin duo Bane is not affected by his venom canisters. -In East End Regal Hotel solo challenge the second time you take Batman down during his boss fight he will refuse to leave you alone, making it near impossible to interact with the switch you have to interact with to move leading to a completely UNFAIR one shot. -In Lighthouse duo Bane will completely stop moving and attacking during his venomed final form making the boss fight rather easy. There is probably more but I can't think of others at the moment.
