Why doesn't lancer disengage (QQ in spelbook) not disable ZC debuffs

In case you don't know, lancer's qq(backblink) disables all buffs/debuffs excluding a scroll and b scroll and ferocity(w). it disables rule breaker/speed gem/link and any other debuff or effect on him. pain and territory explode create an icon on bottom (as well as corpse explode/blind) which are all technically de-buffs.

Is this a bug/bad coding or suppose to be like this?

Originally, QQ isn't supposed to get rid of debuff so it's prolly the latter.

i am not exactly sure, i think it was done on purpose when they were trying to interrupt lancer's skills, also i was trying to find a rune that had some connection to backblink though i didn't find one. this is probably closest ability to it (copy pasted from wiki).

Disengage (仕切り直し, Shikirinaoshi)is the ability to break away from combat.


C: Bonus effect of returning battle conditions to what they were at the beginning of the match

so yeah, they probably interrupted "battle conditions" as buffs/rebuffs put back to default.(lancer breaking away from all effects)
