How much of a difference does the range make with Mist-like skills?

So I was watching some videos and I noticed that Poison Sling had a way smaller AoE than Curtain and Poison Mist. So I decided to take a peek at the data and look at the actual bounds for the skills.

mist 400x300
curtain 400x280
sling 200x170
All are horizontally centered around the point of impact/casting.

I will refer to these skills as "traps," because that's what they appear like to me. I was wondering, how much does the range matter? Do you need to place more than one because of it, or is one per platform enough? Is there a chance for a monster to walk right through a trap without being affected? Hopefully an experienced F/P can answer this, since Mist's range changes over time.

Also, do traps disappear the moment you cc or change maps, or do they stay for the entire duration?

Well, the range would certainly be inhibiting for a mage, but since monsters don't use magic attacks while in Darksight, and since Night Walkers can attack out of Darksight, I don't see the range being too much of a problem. You can simply walk across a whole platform dropping Slings and recasting Darksight while barely breaking pace or getting hit. I'm guessing that Slinging a map is going to focus more on coating the whole map with mist rather than placing it in strategic places, as F/P Mages do.

From what I've seen, monsters get poisoned in about 1 second, so unless the monster was especially fast, they'd get poisoned walking through a sling. I think that himes would be the only monster you'd train on that could run through it. And yes, they stick around even after you change channels.

chance of poisoning relies on time spent inside the trap. higher level skill gives a better chance of successful poisoning so less average time is needed in the trap. lower level skill also has smaller range (for mist..) so chance of monster being poisoned goes wayyyy up the higher the skill level.

there is also a chance of repoisoning for each [time length] spent in the bounds of the trap which makes longer trap time really useful.

mist is fairly useless until its about ~19, +-3. but once its about that level you start getting significant #s of mobs w/ ~1 hp left.

@ emu: if you are going to cc at all, i dont see coating as an effective training method unless spawn density is really low. if youre gonna leech off a bishop at skeles, coating would be effective since you wouldnt be trying to kill, just hit for leech xp.

Range is extremely important for misting, having the large range that it does allows F/Ps to cut down on having to lay down as many mists. Though this won't be too much of an issue for nightwalkers due to the fact that sling is ranged.

You wouldn't want to Sling at Himes because Himes are naturally poison-immune (I know it's just an example but I just wanted to point it out).

sling gets its own element. himes wont be immune.
