Dark Knight as a job has become a mess of skills. Some of these skills actively take away from the enjoyment of the class. Here are some suggestions which would make game play more fluid and enjoyable, hopefully without impacting our place in the balance of tanks. The short of it is that animation locks and double weaving without clipping or burnning dark arts is becoming an issue. The 3.x ideas in the 4.x system are crashing together and it makes for a number of flow issues.
1) Plunge, please decrease the animation lock. Dark Knight thrives on double weaving, which has become difficult especially on the NA server, the server move has increased the latency for many of us and double weaving itself has become difficult, plunge only makes this issue more difficult because of its excessive animation lock.
2) Plunge, please increase the range to 20 yalms to match most other gap closers in the game.
3) Baseline additional effects from oGCD abilities that are dark arts effects/build the mana effects into the skills directly when applicable. 3.x had an interesting feature of augmenting our abilities with dark arts to grant new and additional effects. 4.x has introduced us to standardizing dark arts as a dps increase to moves, usually 140 potency increases. The two systems together don't flow right. Often times the dark arts effect on these abilities only serves to further congest our double weaving.
Example: Carve and Spit is almost always used with dark arts, removing the dark arts effect, baselining the 450 potency, and building the 2400 mana cost into the skill would reduce double weaving and improve game flow. Carve and spit 450 potency oGCD Cost 2400 mana (no dark arts effect)
Example: Dark Mind is rarely paired with dark arts since The Blackest Night and Dark Mind usually mitigate more damage for the same cost (and with the potential to reward that cost almost entirely), removing the dark arts effect from dark mind would have little impact except to reduce accidental uses of dark arts. Even better, baseline the 30% magic vulnerability for no cost and call it a day.
Please leave thoughts and other suggestions below, as always like to show support. I'll update this post with other players suggestions who seem to have community support through the like system.
