SB chakram proc stacking damage bug

[eze]

chak has stacking 200%dmg. (6/6+chak)
chak+krak armor procs = 351k dmg

krak bow has stacking 100%dmg
krak bow+krak armor procs = 351k dmg. (swap to 6/6)

doesnt make sense?

also proc does very little dmg, intended or bug.

one more thing. If you aim shot (5/5 upgrade with armor reduction), it shows the red armor debuff symbol. With krak procs and this weapon, nothing shown so I am not sure if armor reduction is applied. Please confirm armor debuff from chakram is working as one of krak weapon for rog apparently did not work before.
