Restless Assault  

- Restless Assault (Mission and Raid) - Huntmaster Grondo will no longer sometimes cast Frozen Feet immediately when engaged.

We set up between the towers on the frozen river. We have a set of pullers that can track and fade the mobs because they can root.
We have the pullers bring all mobs around and up from the south. We designate tanks for the boss and up to 8 adds. Usually won't get more than four at a time. Kill adds (giants and wolves) first always.
You will have a time limit before the raid fails due to adds killing citizens in the zone (or something like that...only seen it once). Pull boss and adds as soon as possible, except for third one.
First giant, Koldan Wallbreaker, kill original giant adds, then the whole raid should hug him close. He does big damage to anyone not near him after emote. Some deaths can pop a restless dead add, but they don't happen often.
Second giant, Darikan the Ancient, after killing the original giant adds that come with him, the boss will pop three crystal golem-looking adds and go invulnerable while they are up. He does this repeatedly at intervals. Kill adds, then he can be damaged. If the boss stops before getting to raid, you may have to move raid out to him if he popped crystal adds (he stays there waiting).
Third giant, Endaorky Stormcaller, kill the original giant adds (multiple sets, so be ready to kill one set, then pull next set, then next, etc.) then bring boss with last set. Kill him away from last set of adds if you can since the boss will cast a big ae at intervals after emote. Make sure dps and healers are out of range or you'll be ressing a lot.
Fourth giant, Mandrikai, after killing original adds, have raid near boss. There will be rhinos (can't be killed) that stampede at intervals and do some big damage. There are colored circles on the ground that indicate where they'll go. The boss tank can move the boss out of direct lines between the rhinos and the colored circles before they stampede. We usually do a small burn to avoid rhino issues.
Fifth giant, Warlord Feri, has a couple adds and then just straight kill mob. We use this mob for rebuffs, new rods, recoup before the last two giants. There is a mechanic where the mob names players who then must grab aggro for a sec or a random dwarf is deathtouched. Usually not an issue and can be ignored as long as you're progressing through the bosses at a decent pace.
Sixth giant, Huntmaster Grondo, has original adds, then will call more wolf adds during the fight (three at a time, but can call more quickly, so they can add up) . Have the raid close to the boss because the wolves will spawn on/near random people in the raid. Wolves can be stunned/mezzed, but have have off tanks ready to aggro. Kill the wolf adds fast to avoid build up.
Seventh giant, Narandi the Restless, will have original adds, then will split into 4 at 90 %, 45%, and 20% (I think). Have tanks designated to aggro as soon as split happens. Choose one to kill, and if there is not a blue ring appearing under it after about 25%, it should be good to finish off. If the blue ring appears, move to another one until you find one that doesn't end up with the ring under its feet. After the correct one is killed, the real named pops again. After the third time, burn him down.
Good luck!

I dont know how long you get to kill the mobs before the next one spawns but I do know that we have never had one spawn before the prior one and the wolves for it were dead and we have also never had downtime between mobs. (for me it looks a lot like killing the mob and wolf triggered the next mob but I havent wanted to loose xp so much that ive tried waiting around to verify that).
