Glances and Crushes can happen vs. any mob higher level than you. They're just really rare until you get to a +3.
A druid with T4 gear and the right kara/mag/heroic jewelry can hit 34k armor. At that point, a crush from a boss will often hit for something remarkably close to a high normal melee hit on a warrior. With no worries about something breaking shield block to crush the warrior.
The danger from crushes is on a fast hitting mob, where you might get unlucky and eat several back to back. Prince comes to mind. However, a warrior faces the same problem. Crushes on slow melee mobs are fairly unimportant. I've never died to a crush string from Nightbane, for example, because his hits are so slow the healers can adjust in between.
In equal gear, a druid's dodge will be about the same as a warrior's parry + dodge. The warrior's defense miss rate will be a little higher.
The big differences are in block, def stance, and buttons. Block matters some on bosses, but a lot on trash. Like hyjal trash, where a warrior or paladin with a good block value can sit there and tank 6 ghouls and take loldamage. Def stance is valuable against single target magic damage. Not that common, but not that rare either. Generally a couple bosses per tier make it worthwhile. Hydross, Alar (to a point), Kael, Gorefiend, Anatherion. In my mind, buttons make the big difference. Pots, last stand, shield wall, heathstones. A druid can go double trinket and manage a weak shield wall, but it's not the same.
Itemization is better for warriors, but tolerable for feral tanks.
As Malazaar says above, only addition I'd make (obvious, but feel it's worth mentioning) is to pay attention on trash as to the likely lifespan of the mob. A lot of the time, especially in Kara, you'll find you won't actually get enough ticks out of Rip before the mob dies to make it a better choice than FB. If you're using FB make sure you're as low on energy as possible before using it, sub 50 as a rough rule of thumb - the extra energy conversion's so atrocious it's better to use another shred and waste a combo point than convert it to extra FB damage .
Except when pvping. It will bring a rogue out of vanish when it ticks. Extra bonus, Cloak of Shadows cannot remove it. So, don't remove it from your bar. Just have it on a button waaaay down the end, like =, or 9. I think I reserve = for Tiger's Fury... :]
It's an accetable temporal damage boost when wearing crappy gear, especially when used in conjunction with ravage as an opener (Tiger's Fury doesn't break stealth), but its lousy scaling makes it completely useless in raid damage cycles.
Using the energy for another shred is definitely superior dps (~40-60 DPS for 6 seconds against 1-2k damage from a shred (crit)).

Reason: DPS calculation
I think there would be a point where haste rating increases your attack speed fast enough to where you would get better returns on using 30 energy every 6s rather than saving for shreds, but unfortunately that would require something unfathomable like 3k haste rating or something stupid like that, combined with the fact that you do not get combo points from using your energy on Tiger's Fury, it's pretty god awful.
To be honest, Tiger's Fury could be buffed up to 200 damage and it still wouldn't outdo what you get from Shred combo point generation and Rip damage, even considering multiplicative damage you would get on shreds during that time.
Eh, if it were buffed to that kind of levels, and if you've got plenty of excessive agi/crit chance, you could always throw in Tiger's Fury rather than a shred when you're at 5 combo points while waiting for the previous rip to wear out. But you're right though- as it is, it's a moot point.
