There a really good wep in BS for a 2 hand for arms? sword , mace or axe best for warrior.?

Maces are awesome. I use Stormherald, which is the best melee weapon I've ever used, on any class. Stats are as follows:

386-579 Damage
127.0 DPS (speed 3.80)
42 Strength
61 Stamina
42 Agility
Savagery Enchant
Chance on hit to stun the target for 4 seconds (this procs quite often)

Stormherald and the S3 mace are regarded, at least on my server (Illidan) as the premier Warrior weapons.
