Like removing insurance entirely, this change would only benefit big, "zerg" guilds on the field in Felucca.
Members of these guilds are considerably less likely to die, more likely to be able to do something like, carry around 2 full sets both with high-end mods, and alternate between them, etc.
Remember that UO is more item-based than it was. Making insurance less effective isn't going to cure that, it's just going to kill a player's effectiveness, which does not make for fun gameplay.
Faction skill loss, a similar concept, really sucks and I think goes on too long.
