High damage builds with maxed resistances are in general the best; for my heavy though I'm quite tanky and am now going for maxed hold the line, after that comes more heavy gear, so you could say I'm a defense oriented heavy, but really the only reason I have maxed BAE is so that I can have as high resistances as possible since I have 0 cores and barely any Black armor. 81% or higher currently on every single resistance.

I would not recommend more than one point in stim shot no matter what, even for tank assaults, it is just eww to have more since the problem is that you can either choose to heal all that amount with stim shot all at once, making you quite tanky for a short time on a really long cooldown or you can just kill everything before it gets within striking range of you.

Smart target > body fueling as an increase in damage can work wonders late game and even save you the trouble of having your health lowered to the point where BF would make a difference, remember though body fueling can be added for a 3rd slot, and often is provided the crit bonus one isn't. Toughness & Body fueling don't interact as well so there is that.
