I wanted to farm for my totem of the void. Killing the 2 mini bosses is no problem. But I wipe on every main boss but the last one. I end up having to skip them all except for the last one.

The robot kicks my ass with his moving time bombs
The female slows my tank and then proceeds to destroy my dps team.
If I skip her and work towards the last boss, I get destroyed by the spawns on the bridge several times trying to get to him. My pally goes OOM after the first fight and another spawn is rushing to me. After the first heal, the Shammies have aggro and I wipe.

What strategy do you use for the bosses in Mech? I would like to farm some gear there and Large Prismatic Shards at the same time I farm for my totems of the void.
