From what I'm looking at, they're the same stats.
Savage Orc Big 'Un:
M4 WS4 BS3 S4 T4 W1 I2 A2 (additional hand weapon in my case) L7
Savage Orc Boss:
M4 WS4 BS3 S4 T4 W1 I2 A2
Add +1 attack for my Big Uns having two hand weapons.
I'm looking at Quartermaster while I'm at work though, and I think it's wrong (it's saying their stats are identical). I think you're right. The boss gets +1 A according to an internet search. Still, It looks like (in my case with the additional hand weapon) you'd just be paying 15 points for to be able to issue/accept challenges. Seems like a missed opportunity to me. I would think that the Boss gets a bump to his
WS and A so that he stays above his lesser Orks (he has +1
WS and A over a normal Savage Orc) even though they're Big 'Uns. Does him being a part of a unit with Additional Hand Weapons give him 3 Attacks instead of the 2 he gets by default, also...shouldn't his
WS be bumped up +1 as well? I know this all sounds confusing. If anyone has or knows of a solution, can they post it? I know 15 points doesn't sound like a lot...but it's 5 extra vanilla-Night Goblins.
