The powder (assuming this is what alchemists have and I haven't confused the names) has a good range, it feels like stonefist, shoots a projectile out and puts them all to sleep.
Bomb is the AoE grenade you throw, and is shown in the video here if you want to see what it looks like.
Knockout Powder is the close ranged single-target, and is absolutely useless.
Ok, well if has ranged ability that makes a difference. I was assuming it would be more of an short range escape plan than a weapon.
Knockout Powder was, I imagine, designed as some panic-button skill. The character tosses a handful of sleeping powder in a small cone in front of you and will only hit a single enemy. The cost is low and the cool down is not horrible, but the skill itself is.
Knockout Bomb was designed with more offense in mind, as you throw a grenade that explodes for a small AoE radius to put enemies to sleep. It's cost and cool down are similar to Powder, but Bomb is useful at any range.
Before they fixed the double Full Draw bug, yes. After, no.
While the double Full Draw did do a lot of damage, I still hated it. The animation of the skill is so bloody slow, and the damage it insanely conditional.
If the striker's purpose is single-target burst DPS, wouldn't it be better to take Full Draw? Full Draw gives you the highest single target burst damage out of all his abilities (besides MoD).
Yes, this archer build was devised as a Striker with, as I said at the beginning of the video, a little crowd-control for a bit of flavour.
Now follow my reasoning here:
I have the Enhanced Long Shot ring, as I mentioned in the video, which eclipses Full Draw's damage by a large margin since you realistically to not get to hit many enemies with full health in a normal match. Furthermore the long casting animation and longer cool down make it overal inferior to Long Shot.
Leaping Shot can actually do a large amount of damage at close range and is a good evasion skill, but that's not where it shines: Leaping Shot's multiple arrows each can critically hit, and this each can trigger Opportunity Knocks. Therefore it is not in competition with Full Draw.
But let's get down to it: Mark of Death tallies up the damage from all sources against a single target for eight seconds, then does all of that damage a second time to the target all at once. To make it more silly, Mark of Death can even critical hit that damage, dealing even more damage. You want to talk about burst DPS? Mark of Death is king, as no matter what ability to compare it against, it can either do the same damage or more as that ability.
Short answer: Never go Full Draw unless you enjoy the animation or like the "sniper" feel of it. I might add that such reasons are just as legitimate as anything I just stated here.
