I'm so... Squishy.

At first I did... But then I got the Krogan Gladiator and ranked up her Rage tree with the most defensive options. Add in shield boosts from Annihilation and now I feel like a real tank (still have to be careful on higher difficulties, though). Every time I melee I feel tempted to yell "By Grabthar's Hammer!"

Just wish I could get her to rank X and finish off her skills, but once I hit 20 with her, I'll probably switch to a basic class that I've already ranked up through cards.

I've got a rank 2 Equalizer which had been my main goto weapon and has helped immensely. No running for ammo- just keep smooshing.

But,yeah, if you don't spec for survivability it gets rough. I'm just glad I've been able to start doing Silvers without fear of being instantly gibbed.
