The randomness of stats is one of the problems I have with the Axe he sells. As a legendary gold item, the stats are locked and always going to be useful to a warrior.
The stats are not a significant portion of the item.
The Warfare bonus only adds a +1 and 3% damage to ONLY the portion of your attack that hits enemy armor. And even the enemies that actually have armor (instead of only magic armor) have much more health than armor.
The +2 Str is a 4% damage bonus at level 7, and presumably decreases further.
108 * 1.04 = ~112.3 damage. Still not up to what a crafted level 7 offers. Even if we generously add in the full 3% bonus of Warfare to all of its damage, it doesn't cut it.
If you also need the accuracy bonus of the Str, it gets a bit closer, but still doesn't offer a damage advantage. If you have 96% accuracy, and gain the 4% to be at 100; It's another ~4% increase in damage; so ~116.8 effective.
Update: I looked into the numbers more; When equipping a lvl 6 2H with no stats vs a level 7 I had a 4% difference in accuracy (favoring the level 6). This may reduce your effectiveness with the white more. Let's say you go from 100% to 96%; it'll reduce the effectiveness of the white to ~121 average damage. So, it starts to get close again, and you still have overpower from the Legendary.
Basically, use the axe until you reach level 7, but then replace it with a good green or better item. And there is no good reason to be using it at level 8.
