>>713410112There are only two times where you'd ever use Bld+.
1. In combination with Spd+.
2. You're consistently ramming the bonus speed cap on that character and are using a weapon where you absolutely need the extra AS.
In every other instance, +speed is better because its true AS vs conditional. You also should be focusing more on reaching thresholds instead of biggest number.
Also, Canter is for all intents and purposes giving a pair of boots on every unit in most instances. If you can't see how much flexibility that gives you, then we have a problem.
