It should also be noted that in 25 man, we were unable to tank assault bots in phase 3. The first one seemed to be fine, and our prot warrior tanked it (and the following one) ok. But, after the first "drop" of the head, they were one-shotting tanks (for 40K) from that point on, for the rest of the night. No buffs that we could see on the mobs.
Not sure if it's a bug or something, but unless we find something else out tonight, they need to be kited and hit from range. That would leave the melee with basically nothing to do phase 3, except wait for the magnetic core.
