The DPS race to the finish becomes a real problem in Act 2 or more when bosses have disgusting damage and armor piercing disables while you have none of that, not to mention gimmicks like the doctor where you either one shot him turn 1 or face the hardest boss in the entire game.
The final boss gimmick is also a DPS race since killing his adds solves nothing and every adds has nearly 20k armor/hp with stupid amount of damage and abilities, essentially forcing you to arrow storm your way to victory. Combined with high scaling of items, when you are level 20 you find your self struggling, a level later you are one shotting everything in the game.
A bow from level 21 to level 22 had 200 damage difference, a near 100% increase.
