Minor speed increase worked out nicely for me on Gothik/4HM due to I'm constantly moving.

Everything else though I just use +7 AGL.

I use a few different versions of boots all with different enchants.

Boots of the Fallen Hero with run speed (highest Stamina of the DPS boots)
Chromatic Boots with 7 agility (for static encounters)
Boots of Unwavering Will (evenutually Dreadnaught) with 7 stamina

Though all those choices were rather easy, I swap in Fallen Hero for kite encounters (Razorgore dragons) and Sartura for trying in vain to pick her back up before she eats a mage alive.

Very very nice to have in some situations.

Best enchant in game for kiting mobs (same speed as the mobs then).

Constants:
Agility to boots = 7 agi
Speed enchant = 8% speed increase

7 agi = 7 ATP for Rogues
7 ATP = 0.5 DPS

Variables:
Time of fight: 360 seconds
Rogue total DPS = 300 (conservative)

Math:
360s * 0.5 DPS = 180 damage (contribution of damage from boot enchant)

So in order for the run speed enchant to be superior to the agility enchant, I need to make up 180 damage from being able to get to my target faster.

(Damage lost) = {(Travel Time) - [(Travel Time) / (1.08)] } * 300DPS
Set damage lost equal to the damage contribution from the boots and solve for travel time.

Travel time = x

180 damage = [x - (x/1.08)] * 300DPS
x = 8.1 seconds

Conclusion:
For a fight that lasts 6 minutes, if you spend more that 8 seconds traveling to a target to kill, you're better off with the run speed enchant as far as increasing damage.

This value of 8.1 seconds decreases linearly with an increase in DPS, that is if you're putting out 600 DPS, if you spend more than 4 seconds travelling to your target, you're better off with the run speed enchant. The same can be said for a reduction in fight time (180s fight has a travel time break point of 4.05s).

I just threw this together and I may have omitted something important or screwed up my math but if I didn’t, than I find these results somewhat surprising.

Well, rogues get crit from AGI ;-) But as a ballpark figure, that does surprise me a lot. You could almost spend 8 seconds positioning for a static fight (note this time only counts if you can start DPSing as soon as you get there) and anything where you kill multiple mobs, or any movement it all, it looks like a no-brainer. Thanks for that! It's definitely going to be the way to go on my Heroism for mostly 5-20 man stuff.

Run speed is a PvE enchant. I've been saying this for months!

I cannot even imagine playing a dagger rogue without it, too painful.

And if people inspected EJ rogues you'd see we have it to a man. It's been the best PvE enchant for a long, long time.

I've had minor speed ever since I got my rank 7 PVP boots sometime in mid 2005 and I've applied it to every set of boots since. 7 stamina will never, ever be as good. I suggest it to everyone who gets a new set of boots and it's nice and cheap, too.

I suppose it will get beaten out by the stamina AND minor speed enchant in the expansion, though.

The number of situations being able to move a bit faster helps is innumerable. Especially for a mage who runs away a lot. :P

I discovered this enchant relatively late and was instantly in love with it. It is the default enchant for everything that goes in the boot slot now and is trickling down to alts who don't have alternatives (talents, aspect, etc). PvP its great. PvE has more and more fights where it is very nice and even doing simple stuff like farming twilight cultists without it felt like molasses.

Yay!

I've been using +5 spirit for a long time now, and I have absolutely zero problems with movement based encounters, nor have I ever. If I screw up my polarity on Thaddius or die to a deep breath on Sapphiron, it's going to be because I completely missed the effect and am way far out of position, not because I was barely paying attention and got moving two seconds slower than I should've.

I see movement speed as something that the player can make up for on their own, be it by making an attempt to just heighten your reflexes to such environmental things, or making a note that you're slow on something when you're learning the encounter so you pay extra attention to it, things like that. Meanwhile, there's nothing the player can do to make up for those extra stats, they're always going to be adding on.

Count me as another fan of minor speed for pv(e/p); discovered it at lvl 20/21 or so when a 60 rogue looked at my (noob) gear, said "your gear sucks, follow me [to Deadmines]"

It's been the default enchant on my boots ever since.
