First seismic should be removed from the game or its range should be moved to 25M/50M max.
Second, light mechs have ECM, Speed and ridge line to protect them. From an ambush perspective 2 to 4 light mechs w/ ECM using terrrain smartly, could very easily destroy a lagging Atlas or Stalker before the enemy force to engage them and they wouldn't need seismic to do it. A potential counter to lights forming gank squads is to have a murder hole set up where you have mechs set up not moving and they get a 1 1/2 second warning blip to fire if the lights are going full throttle.
