Executioner, Flurry, whatever. Those skills that are efar and beyond stronger than most of the others. And people over use them repeatly.
I think there should be a incremental increase to the cost of skills used repeatedly. First time normal, 2nd +10% more, 3rd +10% of the 2nd's cost, 4th +10% of the 3rd's cost.
Instead of spamming one skill, cheesing the game, make it so they have to use combinations.
I don't really mind dying when I see 1 person using 3-5 different attacks.
A Screen full of Execution? I want to garrote the bastid in their sleep.
