I finished up all the ME2 DLC and imported my save. I went with Infiltrator this time, but I'm not sure I'll keep it. I love the cloaking ability, but so far it hasn't been as useful as Adrenalin Rush. I'm only at Mars, so I might restart. I'll finish up the mission and make a decision. Even if I do keep that class, I'll probably restart and change the difficulty to Insanity.
