There was a plan to continue our 25-man run last night but we just didn't have the numbers, so we decided to split the raid into two 10-man groups.
I was in the saved group that had already killed Leviathan, Razorscale, Ignis, XT-002, Kologarn, Auriaya and Thorim. We decided to go for the Assembly of Iron first. Assembly consists of three bosses. Steelbreaker, steel giant, does an attack called Fusion Punch, hits for a lot and leaves a nasty debuff that must be dispelled. Molgeim, leaves runes of power that buff the other bosses or the raids damage output (you really don't want Steelbreaker to be standing in one when he does fusion punch as it one-shots a tank). Lastly, Brundir, casts chain lightning on random raid member and does a Nova (you don't want him standing in runes either, but he's a caster so sometimes tricky to move.)
I was the tank with more health so I was assigned to tank Steelbreaker, with another paladin picking up the other two. This did not go well, I wasn't able to generate a lot of threat (breaking rotation to dispell the debuff myself) and the attacks from the other two kept killing off one-two raidmembers, inlcuding healers. After a handful of wipes we decided it was best to move on to Hodir.
Hodir started off badly but we downed him in the end. It's a question of dispelling, standing in the right place and making as little mistakes as possible.
We decided to have another go at Assembly, this time switching the tanks, I was taking Molgeim and Brundir. On the first attempt we downed Steelbreaker pretty painlessly so it waslooking good, an unfortunate rune managed to still kill us. I think the key here was using an interrupt on Brundir as a rune of power was cast on him (seeing as I can only do that with Avenger's Shield a Warrior would be better suited). We downed them in the end.
I also won my first piece of tier 8 (10 man legs). all in all we wiped a lot (100+ gold repair costs total for me) but we kept going, kept spirits up and downed them.
