Two simple ideas come to mind.

1) declare the move and shoot, cut the mech's movement in half (rounded up), and add two to the targets defense for the difficulty of hitting something while moving.

2) Make Mechs use speed points like VTOLs. For 3, maybe 4 points, a mech can declare an attack. That would make some of faster, lighter mechs much more desireable. I'm sure there are even other ideas that could use the speed points too if a little thought was put into it.

The one I like best is to allow move and shoot is this.
Make it cost 2 actions. Any mech can move it's normal move and with the second action fire or whatever. then the last action can be used as normal. This is if its a 450 pnt game. Heat and any other results hapen as normal for BOTH actions. This is a simple and easy addition to the rules. If you want to move shoot ,shoot vent, or run-vent, then spend the actions to do so.

I think you are on to something with #1. I would let all units do it (no formations) and get rid of the silly tank drop.

#2 overpowers fast mechs which are already too strong.

Just my humble opinion of course.

I like Idea #2, I say "Let a mech make a move and shoot attack, With the addition of one heat to what it would normally inflict,And a Subtraction of 3(No less than 1 speed) To the mechs printed speed value" I like how solaris is set up, Because You can Move half your speed and Fire, Or you can move half your speed Aim and fire, or you can Move your full speed(or run or sprint) And Quqick shot if that was somehow intigrated into normal mech warrior i think mechs would be more godly as they should be.

Not a good idea for several reasons, the primary 2 being as follows.

Being as using this run and gun you develope defenses and offense moves based using this method. By the very nature of win/ not win you must using house rules of any kind develope both offense and defense around a rule/house rule.

Which leads to great reason #2, once you develope the mentality of run and gun you will find yourself either disqualified or a continual loser while attempting to co exist with the another different set of rules--The Official Rules. And at all the big game conventions down to the local venu official sanctioned tournaments it is the Official Rules and Official Sanctioned Tournament Rules that govern everything. THUS playing anything but the official sanctioned rules will in the long run severly hamper your chances of victory.

Why not just allow all units to move once, shoot once, and preform one special action or
Move twice, don't shoot and preform one special action.

One should never speak for someone else, but I think the idea was to have M&S incorporated into sanctioned play.

Anyway, I think we should look at how M&S is done currently. There are some VTOLs that simply can't do it because they lack the 'points' to do it. Would we do the same with mechs? Like, make shooting with a move order cost 6 points. I don't think that would go over too well. Using the VTOL model is not the best.

The idea of using 1/2 movement might work better. So, would it be a movement order or an attack?

I´ve been playing MK as well as MW for a very long time... and the best way of doing it would be to treat the Mechs as MK Titans...

They can be given 2 Actions in a turn... making them worthy the points and the abilities... but not unstopable, beacuse of the heat...

But that´s only my opinion...

I would have to say that using the VTOL method is the best way to work move and shoot.
Tinkering with it, I found that six inches work the best. Mechs can opt to run if they need to get some extra distance (if a mech had a movement of five, it could run four inches and shoot).
Light mechs, like the locust, would be able to skirt around the edges of a battlefield and harass bigger units. An Atlas, however, will find itself marching to the center of the battlefield, then unloading its massive payloads into anything that came near. Doesn't that sound EXACTLY like how mechs work in all the other universes (CBT, the books, the video games)?
The argument of it making mechs dominate - um, is that really such a bad thing?

This would be RUN and shoot, not move and shoot. I would never be in favor of letting a mech R&S. You'd have some mechs moving 22" then shooting 10" for a total range of 32". I can't see that working. Although it would take care of those pesky SSA4's. ;)

As I pointed out earlier, if we use the VTOL model, some mechs simply will not be able to M&S - most notably the assault mechs - unless the speed cost is ridiculously low. I wouldn't be in favor of that either.

I think the only viable mechanic is 1/2 speed cost, rounded up, to shoot during a move order.

I vote #1.

I just don't know about the -2 attack mod. Vtols don't give this up. Tank-drop doesn't either. I'd leave it as is - simpler is usually better any way. ;)

If you let all units move and shoot at -2 attack, you would not need tank drop. VTOLs could follow the same M&S rule as everyone else. Easy, simple.

I never thought M&S would be a good idea until I played one. Its an outstanding concept.

OK, I didn't know we were reworking the M&S rules for all units.

How would that affect VTOLs? Would they use 1/2 movement to fire?

If it's one rule, it would have to be consistent for all units.

Move and shoot should be handled as 2 actions and require the orders and heat/pushing damage that goes with them. I honestly hope Wizkids does something along those lines and eliminates the SPs of VTOLs.
