Avenger is a bad physical torso. here is why:
very trash heat cap and cooling
extra weight
below average energy cap
and the resistances are below average
and no it's not underrated. it's trash. that's why peopke don't use it.
and second, physiscal huggers to NOT work at all
here we have wingido, one of the best non-premium heat torsos, along with naga
and here we have avenger.
