It has always been that non-humanoid mechs can shield one side of their mech better than the other, but were also
worse at even distribution of damage across their entire mech. Conversely, humanoid mechs are far better at spreading the damage across all sections of their mech, but generally worse at fully shielding one side of their mech from fire.
With humanoid mechs being taller than non-humanoid mechs, one must keep in mind that
height is not what generally kills mechs. Width is, since the mech layout (torsos and arms) and mode of motion is primarily along a horizontal axis, not a vertical one. One does not generally "over shoot" a target mech. They usually miss to the sides of it.
Given most of the humanoid mechs that got bigger only
slightly became wider (if at all) and mostly just
taller, I see minimal impact to that rule as far as the humanoids go. When it comes to the nonhumanoids, the only ones that really had a change to their damage spreadability would be the NVA, CPLT, and arguably the Jenners, as they had a fairly significant size change in both the horizontal and vertical axis.
