While among the Clans the Watchdog CEWS is dubious (because of it weight and size, and because Light Active Probe and standard Clan ECM suite is actually a better combination for equal size and mass), for Spheroids it would be nifty.
Pull a Guardian or Beagle, and slap a Watchdog there. You lose range, but you gain both capabilities.
Would be actually nice here. Replacing some Guardians with Beagles is a possibility, but then you need two 'Mechs to get both functions on the field at once.
I'm actually a fan of your Active Probe suggestion, and it'd be pretty easy to scrounge up the extra half ton for that.
? I was just suggesting replacing the Guardian with a Beagle for a sub-variant/field mod, not in addition.
