^Good luck charging and nova'ing that last wave of Banshees! 
My current renegade maleshep is a vanguard too and so far I'm pretty bad at it. I had this problem in ME2 as well. For some reason I can hardly ever hit anything with a shotgun. Got so annoyed that I started a new game with my paragade femshep infiltrator to relax. Boom, squish, headshot! Fun.
BTW, anyone know how well edited ME2 saves have been fairing? I have a femshep I edited to romance Tali and I'm curious to see if it will work...but I'm not playing half the damn game to where she shows up just to find out it doesn't. :/
