The RAW don't directly substantiate this interpretation, but they certainly provide support for it. The point is, that line is open to interpretation, and even WotC's own staff think it's more reasonable to interpret it as widely as possible - that mithral medium and heavy armour is considered one step lighter for all purposes - than to interpret it as narrowly as possible, as you are doing.KarinsDad said:The point is that RAW does not directly support this interpretation and WotC has yet to errata it. Your own quote here even admits to that.
Either interpretation requires that one extrapolates from the bare "for purposes of movement and other limitations" line.
WotC's interpretation has the advantage of causing fewer inconsistencies, and being far easier to use in actual play.
Your interpretation has the advantage of... letting you use this particular item on mithral full plate. That aside, it's hard to see any merit in it - it doesn't seem to make gameplay any smoother, nor does it seem - to the majority of posters in this thread, or to the people who wrote the game - to be a logical and consistent extrapolation of the rules.
