I've been trying to beet classic mode on insane difficulty for the past few days, and I have had no luck beating it. Farthest I got to was defeat by Metal Bros. with Peach. But, its not that is the problem, it's the allies you get in the 2v2 match and giant vs 3 match. The allies will hardly ever attack, they will recover (or try to) but are usually easy to be killed, leaving the player to do all the work. Also, I noticed that if the stage being played is Temple on this difficulty, not only the ally/allies will just walk and jump around where they are, but the enemy/enemies too. The only time the enemy/enemies attack is if the player gets close to them. I'm not sure if any of these things are intentional or not, but if they aren't, please fix these issues.

who knows, maybe it's intentional, but hell it's irritating either way because it feels like you'll have to do 1v2 2 times in Insane

Can't help but wonder if this will be adjusted when the Peril Roulette rolls around.
