root and nukeFollow

i took this from planeteq





so does this mean that when you nuke a mob that is rooted that nuke can cause root to break?

i always thought when the root broke was random

The root timer is random in a way, but by the time you have maxed you casting skils it will be either a) sticking for its stated duration b) breaking early on its own c) breaking early because of hits taken by the mob (including your casting)
Which of the three is more of a function of your level, the mobs level and if someone else is bashing away.
I have clicky pants, Ornate Leather with Savage Root, which lasts 4 minutes. I also have enhanced root as an AA. I would say most of the time, about 75% to 80%, the root lasts the full four minutes unless the mob is molested by someone. Furthermore, I can nuke mobs I have rooted and a little more than half the time the root does not break.
Lower level mobs, like four hands in ME, I can root and nuke to death without it breaking at all, but not always.

AFAIK, DoTs have a (lesser?) chance of breaking root per tick, ie each time any damage is done. So root breaks on these conditions:

Direct damage
DoT each tick
random break

Should probably look into the exact effect of DoT dmg vs Root.

I have never seen a DoT break root. I have noticed that different DoTs hit the mob is different ways graphicly, but I have never had a mob break root. I use clicy wrist (Drones of Doom), Epic, Immo of Ro and Swarming Death when i am root rotting. I will add Winged Death if there is a need to kill really fast. I have yet to see a connection between the root breaking and the DoTs hitting.

I have my specialization set to Alteration (which Roots use) I dont think this does more than give a chance to reduce mana cost and fizzle rate, but I am not sure.

I think you'll find that only the DoTs with a DD component like shaman and necro ones risk breaking root. Druid DoTs have no DD and can safely be applied without affecting root duration. It is still random and depends on relative mob level.

I have also found that druid root seems to last longer before breaking than the cleric/shaman line. This can only mean that the % probability of breaking is different.
