Nerfing Range?

[Knox]

Hey all,
I'm thinking about playtesting a rule in which figures cannot use a ranged attack if they move more than half their movement. For a lot of 'Scape figures, I think this is pretty realistic - loading and aiming time would've meant that the minutemen, for example, wouldn't be firing unless they were stationary.

I love heroscape but the range-dominance means a lot fewer of my figures get used - and most of the fun of heroscape is the variety! Would anyone be interested in helping me playtest a rule like this, to help melee units get closer before range is able to mow them down?
