So ive looked at the bladedancer skills a bit more with some gameplay vids, the arcblade will be intresting in how it is used, depending on certain skill combination your build will become highly situational 1) Wave killer- Arcblade with razors edge (shoots narrow waves) there is damage drop off over distance, but this skill can easily crowd control in narrow areas. ---a)Paired with ENCORE you become a formidle wall in these corridor situations, multiple kills will replenish your arcblade. allowing you to push back wave after wave ---b) Hungering Blade allows immediate health regen on kills means you can stay in the firing line for longer, against stronger foes this might be a better build. However your arcblade use is more limited and you will rely on a sunsinger to reduce your cooldowns. 2) Crowd killer- Showstopper an arcblade that causes radial damage (DOES MORE DAMAGE THAN RAZORS EDGE) you are risking being up close and personal but can take down groups with ease. ---a) Encore is maybe viable here, if you play smart and use the environment to your full advantage, maybe even the better slide skill aswell you will become a serious force to be reckoned with. ---b) Hungering blade, again faster slides and movement will boost this build, you may have regenerating health but you are far from unkillable, as a build this can stay in firing lines longer and is more built for high pressure situations. 3) Healer/Stealth now this has many many combinations depending on how good the stealth mechanic is, blink and blinkstrike work, aswell as how fast the health regen is, based on stealth activation from arcblade this skill wont be as readily used as your blink and blinkstrike, these will be your main escape tool. Blinkstrike can be used for to create a short duration cloak, but this is more for escape purposes in my opinion Blink strike- Now this skill is intresting, its an extended melee, and works with hungering blade for health regen. The only two sensible options would be fast twitch (shorter cooldown) if you want to stay alive. The other option is escape artist (temp cloak) which with a high recovery build this may be a better option for an ENCORE build.
