Low-Stat builds will all win?

Shroud of zakum is still pretty eh unless you are a mage then, I can't think of any good reason I would use even a 3 attack pink cape (at best with 2 30% on it, the cape would have + 12 stats) and 3 attack is better than 12 stats.

True.
But with 7 slots you could try for 5 30s and 2 60s. Which would be 22+ to the main stat.
