167 chart, if the claw on a heavy suit lets it use mechanized rules but can't let it perform Anti-’Mech attacks (the claw's only other function) due to the suit's weight class, then what purpose does a Heavy Battle Claw have over a standard Battle Claw? I flipped through just every one of the core rulebooks and couldn't find a notation that differentiates between the two types except for the mass in the construction rules. 167 says a heavy suit (which is what I'm concerned with) can't make Swarm or Leg attacks (which are the only Anti-’Mech attack options listed in the TW rules) and needs a minimum of 1 Battle Claw or 1 Heavy Battle Claw.
229 says a battlesuit of certain weights with at least one of either of these can make Anti-’Mech attacks and can use mechanized battle armor rules. What is the qualitative difference between a Battle Claw and a Heavy Battle Claw on battle armor? TW p. I figure this question is worth asking since I spent about an hour or so the other night trying to figure this out but ran into a dead end.
