on classic you can build half optimal party and literally sweep through everything so far half asleep.
The whole Internet would gain a massive improvement on the information-to-noise ratio if people wouldn't engage in such stupid hyperbolic posturing.
I have no idea what are you so triggered about. Reality is people are doing it, it is difficult and maybe dumb kind of difficult, but it's supposed to be a challenge, because ultimately classic mode you become so OP that you can roll that one even not min maxing.
And this is the only real challenging alternative to classic, unless you are a total Edgelord.
And yes you should be optimizing, be clever and fight dirty there, it's called tactician for a reason. I have a feeling half of the people complaining expected to just waltz in there and mop shit up because they think they are so smart.
