Man I'm am sorry you had a bad experience but just look at the posts on here about deer that have been taken and you'll see that trad gear is more than adequate to achieve a pass thru. I cannot speak from experience as this is my first season with trad gear, but post after post shows pass throughs on deer, hogs, elk, moose, you name it. I don't know what your set-up is, but if it is tuned well, I'll bet it has the energy to send a sharp broadhead through a deer. You are not going to get a pass through on every shot, but they are certainly not uncommon.
Give yourself a day or two to calm down and then re-evaluate. Check your tuning, check the sharpness of your broadheads, etc. I am sure some other more experienced trad hunters can give you example after example of pass throughs with even light poundage bows.
Hang in there,
Mark
