Because it makes Stacking Fit kind of silly and useless. Why get both if you can just use the coat and helm/arm protectors/socks to get a much higher bonus?
I mean, getting both theoretically has a higher bonus, but only once you get superhuman strengths so that you can stack all the armor bonuses. And I guess it helps if you don't want to wear a helmet.
No it makes it Armor appropriate for the Environment you are in... not to enable armor stacking cheese. The game has numbers it likes to hang around... getting a full +7 is for a Str 3 character while everyone is dressed atrociously isn't the goal. Anyone who Stacks Sleeping Tiger & Synergist Line Coat should get Distinctive Style when they do it & a point of Notoriety the second time they wear the combo for their fashion sense offending everyone who looks at them.
No the ruling makes the qualities Custom Fit and Custom Fit (stacked) mechanically nothing at all. Literally no different than any other armor, except for characters with greater than what ....10? Strength? I can't imagine the intent was to buff Troll soak totals, and only troll soak totals.
Anyway, simplifies my armor choices if ever I manage to show up for a Missions run at a Con I guess.
Shields are ?7? Helmet of 2, Forearm guards, Secure tech.... total of 12 if memory serves? So, need 11 STR to need Custom Fit (stack) to actually matter. Or like a 18ish Agility I guess.
Yeah, silly ruling. *shrug*
