Legendary Ash:
Any distribution of power (armor BRS%) that includes status conditions/combat effects are balanced as long as it totals 1000% in 10 turns, which is the minimum turn model, the standard being the 20 turn model.

Its not a good idea to directly modify standard equipment BRS% values since other equipment types may expect a value and will result in imbalance when that assumption is thrown off.
This is the case with the Server caps on multiplicative LS rate boost standards, additive LS rate boosts are relatively weaker (blue cap) and stronger (red cap).

Luk stat, additive LS damage and rate should be the only variables allowed to change if designing such equipment.
