Frozen ManaclesFollow

Maybe someone can help me here, i read on Ogaming that frozen manacles was a must have, i just got it myself at level 19 and its a:

0.5 second root
+ 20-30 damage or so
cost:33 mana, recast time of 9second.

Now thats the most useless spell i have got since i play everquest 2 i think, anyone can tell me why i see people drooling over it ?

is upgrading that spell making an insane difference ? cause i never saw an upgrade play on duration so if it stays at 0.5 sec, whats the point ?

Maybe it does last longer than 0.5, just saw duration 0.9 sec and recast 9sec, maybe it is a mistake tho on the app 1 description, but ill take it for cash if people do agree that it is a good root, the effect is certainly really great :) much better than arcane bindings

The duration posted in the spell description is wrong. I've never bothered to time the duration myself, but at App II its just a little longer than it takes you to kill a mob with your spells (including your HO ability), provided you manage to avoid interrupts and fizzles. So if you're using it to split a pair of mobs, you don't want to take any longer than you have to.

And its somewhat unreliable if you're doing damage on the target. I don't think a pre-existing DoT will break it. I've tossed Whorl on a mob, and then rooted it, and never had the spell break while I was getting more distance between myself and the mob. But any damage spells that land while Manacles is up have a chance to break it. Sometimes you'll manage to go through the entire fight and not have Manacles break. Other times, you'll have Manacles break when your first damage spell lands.
