It's an easy enough thing to try out. The original reasoning behind the lower multipliers between campaign & RTS was that we wanted to give every player a chance of making a difference through skill-based play. The higher the multiplier, the more that goes away, but indeed, I can see the case for it.
I think we might be best off attaching a slider to this one though, because I'm sure not everybody will want to be chance less in battle, especially the players who are participating without any starting units in 4 player matches.
