The reason that they would break the game is that it is "easier" to out maneuver a tank than a mech. Think about it kjones, the tank has to transverse the huge turret and even then if you're close enough the turret can't target you. Now a mech can not only bring it's arm mounted weapon to bear, but it can kick you as well.
Stop Right There.
Real Life Physics does not apply to Game Physics. Turret rotation speed doesn't mean squat. Power sources don't mean squat. Arm weapons don't even mean squat either, because shadowrun treats mechanical limbs with a strength = body+0. No extra damage, no AP.
Seriously. +1 handling does not break shadowrun in any way. The half-Speed from walker mode hurts even worse. The -important- benefit is that you get to use your Speed as your Movement rate - its your reasonable, top-end speed for someone who's using their legs. (also, supported by the cyborg rules, which do this automatically.)
If you want to argue something's Gamebreaking, break out arsenal, and use your stats. I'm going to go with the Dodge Guardian, since it seems about right - decent armor, decent body, gunmount, and a speed of 50 seems to be about right for a tactical stompy robot game.
This isn't a 'how unrealistic are mechs' discussion. They are. We all know this. Tanks do it better in pretty much every way, and this topic's been debated to death across half the internet many times before. The topic is 'how to stat it in shadowrun.' So get to it.
