I really hope they reverse this decision for many reasons.

The most important of which is the fact that PVP gear which was intended for PVP content in the first place is completely useless in frontlines. Morale doesn't work so you lose an entire stat. Okay. So the PVP gear you spend a while to save up for has no effect. Cool. Well, at least I can use it for glamour so I can look cool while kicking butts in frontlines. Oh, I can't, because glamour doesn't work in frontlines.

So the gear is effectively completely unusable.

Please allow glamours in frontlines since morale doesn't matter and what you see someone wearing has virtually no purpose.
