Ahh, I forgot you can't specialize in the tower shield. That's a damn shame.
Also, I didn't realize the frenzy gave you -2 to hit with the extra attack (I've never seen the ability, was just using the description other people gave). That does make it much less attractive, though the AC bonus and the fact that the extra attack is optional is pretty cool.
BTW, the reason I was using medium armor was to keep the +10 movement from the barbarian level.
Ok, so screw the tower shield... +2 AC and -2 attack can be accomplished with combat expertise anyway...
Dwarven Barbarian 2 with heavy shield, shield specialization, breastplate and frenzy:
Dex +3 armor +5 shield +3 frenzy +2 = AC 23
Attacks:
Str +3 BAB +2 frenzy str +2 WF +1 MW +1 = +9 or +7/+7 at 1d10+5 each
Old Gumphrey, you gave your fighter 18 strength, I was specifically staying away from that, since few people will really want to spend so many points on one ability score.
Anyway, even without the tower shield (booo! I was hoping there might actually be a use for the thing...) AC 23 at level 2 is *hard* to hit. This guy only hits himself on a 14+ even while frenzied and not taking the extra attack. That's pretty harsh.
