Like i wrote in the "Mech targeting" thread, alpha strikes in combination with sniping is so deadly because you hit exactly what you are targeting at. If you look at the board game, shooting a fast moving target on high range while jumping resulted in an extremely high modificator, that made it nearly impossible to hit the target. However in Mech4 this could be easily done. Jump -> aim -> shoot -> 4 large Laser hit all the same Zone -> target heavily damaged / destroyed.
In my opinion, a mech with jump jets should only gain an tactical advantage off more mobility in heavy Terrain. So make it that your Crosshair shakes like hell when you are jumping and we are all fine :-)
ARES, I asked a question about weapon accuracy a while ago, here is the answer I got from Death_Grin, a dev on MWLL:
My question:
3) Will there be a cone of fire in the game? [Again, for example, part of the fun of Battletech was rolling to see where you would hit the Mech. In Mechwarrior 4 everything always hit wherever the reticle was pointing. Also, games in the Tom Clancy franchise lose accuracy the longer the weapon is fired, for automatic weapons anyway.]
Dev Answer:
3. Yes, bullet deviation exists already in engine and was used for every projectile type in game. Certain weapons are more accurate and have a tighter cone of fire then others. So, for example, if you are using a failry inaccurate weapon (wide cone of fire, large deviation what ever term you want to use) and aim at the head there is the possability of hitting other parts instead. The ballisitc trajectory is calculated by the game engine and depends on several other factors as well such as wind velocity and gravity.
