Under some circumstances Offense set does more critical damage than CD set

For reference i compare the sets using the following formula (simplified for full gear tiers): (1/(o/(u*.15))/(cd/cd+30)=cc
cc=breakpoint where cd set surpasses offense set
o= offense including mods but not the set bonus
u= unmodded offense value.
cd= crit damage from mods abilities buffs and leaders.

The more offense secondaries and primaries you have, the lower the value of the offense set. Other offense increases don't affect its relative value since they are basically all multiplicative (qgj lead being the only exception I can think of since it adds an amount of offense unaffected by your current offense). The more crit damage increases you have from anywhere, the lower the value of the crit damage set because it is always only additive (the amount of crit damage that gets added is never affected by your current crit damage).
