What I meant in saying that it was hard to gauge exp in combat was more to the effect of what a specific message on a weapon was. Like does combining ice and fire at *2 make a big difference in the exp I'm getting for those crits versus *4. Not just looking at how much my exp went up after a combat round or two. Sure you can gauge in general which weapon is better but not actually figuring out what components of the weapon are being most useful.

And as Ganelon was getting at, if we can just calculate it anyway it's going to ruin the "magic" for the same people that would want it displayed. At least newbies can see what their looking at instead of vague crit messages.
