It would be neat if two movement systems allowed you to assign one of your own

to the melee target, similar to how you would add someone else's

for a "spot." This would create two major issues. First, fast melee now does more damage, when melee damage is already more dangerous (easier to wound). However, a melee mech with TWO dedicated move systems is much easier to gun down. He's already easier to get into position, but less useful once he gets there. Second, dedicated "non-combat" units like this guy

now have a decent melee attack. CRASH!! In fact,

+

on average would be stronger than

. Perhaps the attacker, in a charge, takes a hit himself? I suppose there are a couple of ways you could handle that. Either the hit is as strong as the

you used, or it has something to do with the target's current

and/or remaining hit points (systems). The latter would make fast melee strong against lighter units and damaged mechs, while armored melee would be better at taking on larger targets. In principle, I like this distinction. In practice, the idea might be too confusing to implement, even though it is similar to the spotting system which is already in place.
It would be an interesting house rule at least.
