Graal LightFL_vs_MeleeDK

Light Caster Freelance vs Melee Dark Knight, while also observing Melee DK vs others, at the end of my "fight". I don't understand why people complain about my class, because the 600 ticks do nothing to most classes, especially since I need to stand still while casting, making myself a sitting duck. Also, even if my attack ticks only once, and deals it's very low 600 damage, my skill STILL gets placed on a cooldown.
