My 70 Rogue with a mix of Kara and SSC gear had no problem clearing most of the dead side. I boosted my main team there qiute a bit. I wiped after Ramstein a couple times and then just started doing runs until I killed the guy that drops the key to the side entrance (Magistrate). The only thing to remember on the dead side is to be careful when doing the Baroness. For that fight, you have to leave your lowbies right after the gate that starts the 45 min countdown. Otherwise, she will MC your 70 and obviously wipe you. If your lowbies stay back there, she won't MC anyone and your 70 can kill her easily.
