I did a search and didn't see this information posted.

I am thinking of getting another mongoose enchant but I would like to know if the enchant stacks, can you have two up at once?

Is there a hidden proc timer with mongoose that prevents it from proccing back to back and would that apply to the mongoose proc on a different weapon?

If you look on worldofraids.com forums you will see posy by Teza (one of the admins, if not the admin) that confirms, D/Wl enchant stacks. Here's a link: Dual Mongoose

They stack and there is no cooldown - proc's can refresh.

Its crusader with agi instead of str. and haste instead of heal.

Well Battlemaster enchant is similar to Crusader as well. (healing-wise only).

Speaking of Battlemaster. Would anyone that has the enchant elaborate on amount of self healing you do during one run in any instance. Enchant should stack with different party members if they have it. And would you put it on the tank's weapon and then stick other melee in his group? Or would you opt for Agi =dodge %age instead for mt?

From what I've seen both from my own Mongoose Enchant, and that of one of our tanks, Mongoose is not only the best Melee DPS enchant, but the best tanking one as well, much so over Battlemaster. In a raid environment the small heal on the MT is relatively insigificant compared to the raw midigation a tank gains from Mongoose. Armor, Dodge, and a bit of crit; the latter being insiginificant compared to the first two. The uptime on Mongoose is amazing as well, if you or your guild bank can cover the void crystals, I would highly recommend the enchant for your tanks.

I thought that there was some speculation that it changed weapon speed as opposed to applying haste?

There are far better things to put in a stacked MT group than an occasional tiny heal from a rogue (shaman for totems, paly for aura, lock for imp buff, druid for tree buff, etc), and the rogue would prefer dual Mongoose anyway.

True, but from what I've seen some people come(melee classes) come out with healing done in thousands in 5 man instances. For example quote of the Healing done below: (note this is not my log I am just trying to look at all angles for this enchant).

Comments I am looking at are from wowhead.com and wowhead.com look at the screenshots of proc watch.

Threat generating ability of this enchant may be worth for 5 mans but I doubt its viability in raids. As I've said before I would opt for mongoose for mt. But battlemaster may still have its place in the game.

I can confirm this, some preliminary testing I did last night definately showed the weapon damage actually going down when the proc was up, maintaining the same weapon DPS, just reducing the damage and weapon speed.

I'd like to see some testing on this also before assuming it was true. The testing in another thread regarding lifebloom showed some unexpected results.

This makes me think of "Cobra Reflexes" new King B ability that gives it 30% passive haste while lowering damage each swing does, did they cross wires somewhere

I don't think any blue posted when it was brought up on the official forums, but it is unfortunately consistent with the tooltip, which doesn't mention haste rating. An argument might be made that since enchants are now presumably designed to scale with level, haste rating was avoided, but it would be nice to see a blue response.

The page for Lightning Speed and the subsequent page for Mod Attack Speed seem to suggest constant dps, although I don't understand why they would do that at all.

Not really; it's a 2% speed increase. I'd think the 120 AP and 3% crit bonus would more than outweigh the insignificant white damage loss.

It's still a good enchant, but I wonder why they even included the attack speed boost if it keeps white DPS constant. I guess for the offhand enchant for CP.

Wouldn't this make it exclusively a tanking enchant, if it lowers the strength of, say, Sinister Strike (lower base damage, right?) but increase the strength of say, Heroic Strike, which is on-next-swing (what with the flat +aggro).

Improves rogues (poisons, CP) but doesn't do as much for warriors (constant DPS) would be my guess. I'm not sure I approve of it, but that would be my bet on why it was designed that way.

(Incidentally, it'd be quite easy to test if it affects SS - it just requires a Mongoose enchanted grey weapon, so I doubt we'll see any testing of that kind of thing until someone gets to it on test.)

It doesn't decrease the strength of instant attacks at all. What it does is that it decreases your swing timer, therefor the attack power calculation for white attacks (AP/14 * WEAP_SPEED) changes (not the base weapon damage however). However instant attacks are normalized and not affected by weapon speed.

The 'haste' component of mongoose is there to increase poison and combat potency efficiency. So basically they made this enchant while having rogues in mind.

PS: yes i have it on both weapons and i get 2 buffs.

Why is there no Crusader upgrade/replacement? Because this is not it.

Dual Crusader still gets you as much AP on a double proc as dual Mongoose does for Rogues.

If it's really like that, that's really weird... could more people confirm it?

For normal haste effects haste has no effect on how hard your whites hit, it just makes them hit more often - the AP contribution always uses the unhasted base weapon speed.
