Currently the game’s difficulty is like a dynasty warriors if the enemies in it had 10x the hp, your average enemy poses very little threat and yet is super tanky. I believe the solution would be to reduce both player and enemy health and then make the enemies more aggressive (with faster attacks too) at higher difficulties.
Right now enemies do too little damage to pose a threat, with attacks that are easy to dodge that you don’t even really need to dodge usually but you still have to whale on them for far too long.
I find that enemy HP and attakc slaces far faster than I can unlock them wihout EXCESSIVE grinding. Terrible IMHO.
