That in itself is the problem. Who thinks that fire and forget extended duration buffs are even remotely interesting in this day and age of game development?
Any skill that's best used with a macro that casts it and then replaces it with something more interesting to use is inherently flawed by design.
PvP Protect is inherently better designed because I get to think about when to use it and that actually matters. PvE Protect is effectively a passive thing that I put up and then forget exists for the entire dungeon.
