Ohh sorry i didnt realize that you gonna play in turn based mode. If so, then yes - youre right, brof isnt suitable for you. In RT, every AP makes difference... huge difference.
About more critical, its not a problem, bacause 3lvl perk you can take on 4th, or even 5th level without any bad consequences. You just have to remember, take it before 6th lvl, cause if not, you lost that first perk.
Suggestion about BRD instead of critical perks is reasonable for me. BRD + BRD + MRD is pretty devastating anyway, you dont need critical bursts (but i have to admit that havent tried critical bg this session, so maybe im assuming wrong).
You can also mess with 5 st + weapon handling on 3rd lvl. And then give up with small frame, so = you have +1 SPECIAL point, and more carryweight. If you want to mine a little (which you want, considering beeing BG crafter lvl1) this can me nice. Downside is -2HP, but its minor thing i guess.
Also, if you want to play TB, i suggest to take Bonus Move at some point. Those 2 AP are great if you make ambush in some city tile - you have exactly additional points to step out, shoot, and hide around the corner.
