Very few games prohibit pre-measuring these days, 40k has allowed you to measure for years.
We have done it in a few games of epic (mainly because we forgot you couldn't) and I don't think it gave anyone an advantage to anyone.

Very few games prohibit pre-measuring these days,

Warmahordes is the only other one I am aware of, and it gets fairly annoying trying to remember that.

My view has always been that the game should be testing your skill as a general, not your skill at judging distances from an omniscient vantage point above the battlefield. Especially when the scale of miniature wargames is so wonky to begin with.

I would say to allow pre-measuring, soldiers know how to judge range, and its their business to know the effective range of their weapon system. I should know, ive been in the Infantry for 18 years!

Take the Javelin AT weapon for instance, when you look through the sight, put the crosshairs on the target, it gives you the range. All snipers and MFC'c and FOO's are equipped with laser range finders as standard.

The whole idea of guessing range is silly.

I have swung around on this over the years. I used to be staunchly against pre-measuring.

I've gone back and forth, too. I'm so used to it now, because E:A allows it. I don't think I want to go back to no pre-measuring. Plus, as others have pointed out, technology supports pre-measuring.

Having played both ways with Epic and 40K over the years, I suggest allowing pre-measuring. Banning it achieves very little, and it's hardly giving either player some kind of massive advantage.
