In PVE, the universal combination you see in almost every build is a weapon damage glyph on an infused back bar weapon. This combo works to keep the enchantment effect up almost all the time. But if you place a status type glyph in its place the effect is messed up, at least it was messed up when I tested it

Years ago a poison glyph on a back bar infused weapon would proc from ground AOE damage every two seconds with perfect consistency. Today I tried with a flame glyph on an infused back bar bow using endless hail and the proc seemed like it was totally RNG based. Sometimes every two seconds, sometimes every three seconds, sometimes it waited four seconds, sometimes it waited five seconds.

Is this inconsistent glyph proc a new bug or a feature?
