You guys talk as if they changed Gladiator from a tanking role to a healing role... I'd feel more sympathetic with this request if that was the case

But conjurer was THE healing class from day 1, with THM being the dark-magic class who can also heal a bit so that we don't necesarily need a conjurer in every party. If you failed to see this then it is your own fault, the game's originally intended role for conjurer has not changed...
