Since BLEED is not an ELEMENTAL attack type, compared to FIRE/ICE/LIGHTNING/PLAGUE it should be allowed to happens together with 1 elemental status.
Thus said, SOMETIMES it happens to work this way, sometimes it is overrited.
I mean.. we experienced sometimes to have a target on fire, PLUS the bleed effect (we saw both the orange damage from fire and the RED one from the bleed while moving).
And sometimes, there was fire, then the bleed filled up at 100% and overrited the fire, removing it.
This should not happens.
As said, again, bleed is not an elemental attack and it should be allowed to stay together with 1 of the other elementals. After all, the elemental damage happens whatever the target does, standing still, moving, running, attacking, ecc… while bleed happens only while moving and technically…it is a physical status effect…
