The old Dreadnought rune allowed for clumping of mobs to maximize damage, but you had to be mindful to charge at the right angle and distance to carry the mob with you, and to reset Furious Charge (FC) cooldown. That decision-making leads to a short interval between FC.
The new Dreadnought rune loses clumping property, but you no longer need to worry about screwing up a FC. The end result is much quicker FC spam, and much smoother gameplay.
