Im usually against anything that lowers the differences between separate characters in a party.
Because that leads into treating the party as one single entity instead of a group of individuals.

But then again, this is one of the "support skills" that isnt directly related to the majority of gameplay...
And it doesnt have much of an influence anyway, as it gives you only relatively small value stuff - at least as far as ive seen.

If the problem is the necessity of switching gear to gain benfits from it then it probably should be removed from the gear effects.

Maybe it could be just a character skill and in that case some additional benefits could be added to it, just like in the Epic Encounters mod, where it also improves combat rating, critical chance and some other benefits.
