I'm somewhat surprised by that statement. Does a druid spamming faerie fire really generate that much threat? I have to put some work into kiting oozes, but it never seemed that difficult unless you have multiples of them running around.

Somewhat depends on your latency, I suppose. If you're confident about your delay you can easily judge while you kite (Judgement of Righteousness hits considerably harder than Vengeance sans stacks), which eliminates any threat issues you might have. As long as your holy paladins took off Righteous Fury, anyway.

Actually you have to be careful about judging, since their melee range seems to be further than judgement range. I usually just judge once right after I taunt when they spawn and they're still thinking about who they are and what they should be doing. After that it's AS and Exo on CD (PoJ and HoF give you plenty of room to stand and cast whenever you need to) and cast consecrate whenever it's convenient.

Based on kiting experience ever since Rotface hit live realms, no, their melee range is not further than your judgement range, unless you have high latency. It's pretty overkill considering it's just healing threat you need to outdo, but it does have the added benefit of keeping divine plea up. The catch is that if you stay close enough to judge, odds are you'll find yourself in melee range when you get vile gas'd on heroic. Cancelaura'd bubble works great for that occasion, though.

On a more general note, paladins have an easy enough time (just like any other tank, really) picking up oozes but we have the unique ability to not only get through slime pools on our own on heroic, but also the ability to control the cleansing. In practise it's probably best to put your tank with the most situational awareness on kiting duty, whatever his class is.

You cannot go travel form indoors. They do, however, get 130% movement speed in cat form.

Pretty much this. We're one of the best classes for slimes just due to our arsenal of abilities:
-PoJ for faster movement
-Judgement and AS for ranged threat (make sure to use SoRighteousness for the double seal proc!)
-Consecration for extra threat as you kite
-BoF to get through ooze slicks
-A taunt that does actual damage, for those "accidental" Big Oozes
-Bubble and Bubblewall in case you get Vile Gassed into Big Ooze melee range
-AD to save you if it happens again
-Cleanse to control ooze rates

Threat on the oozes is pretty trivial as well. They don't attack for a few seconds after they spawn, so you can do the following:
-HoR on spawn
-ShoR, start running
-Judge as you're running out to range
-AS at range (by this point the ooze should be active)
-Drop Consecration in the path

That gives you enough of a threat lead to last the full duration of the ooze, in my experience. I still slip back into Judgement range on occasion to refresh Divine Plea, but even that's not usually necessary. If it is, try and time it for right after a Vile Gas cast, so that you're in no danger of being stuck next to the ooze. Also note that you can keep moving in between ticks of the vile gas.

A FFF actually causes more threat then the initial hit from a Lacerate.
(Although the 5-stack obviously generates more tps over time.)
Thats why druid tanks keep it in their rotation even on targets they already have agro on.

No-one ever took points from vindication and 2% crit pales completely to moving 6% faster.

To clarify and give correct information, it's not 46 AP. It's 574 AP at rank 2 and level 80. Either way, the point stands that it's really not a negotiable talent unless you ALWAYS have someone putting up an equal AP reduction for you.

The information about the Engineering boot enchant is incorrect. When they backfire, there is a 100% chance to get launched into the air if and ONLY if flying mounts are allowed where you are. If this does occur, there is a small chance that you will never receive the parachute buff, but this doesn't matter unless you're tanking for a group quest outdoors. If the boots malfunction when you are NOT in an area where flying mounts are allowed, then the "malfunction" will do absolutely nothing, besides wasting your 3 min CD.
