What are you talking about, not competitive with balance? It's not competing with balance. You can't decide to use balance instead of spear, you get one or the other. If it was the same as balance, it would be both immediately better because it interacts with healing and crit-based mechanics, and equally boring.
You can't say "I don't want spear, I want balance", and hey presto. There is now an opportunity cost to giving up a spear in hope of balance that didn't exist before. If you get spear, and reroll it hoping to get balance, you absolutely lose on average, even with base levels of crit. That choice only gets worse as people get more crit.
