Sad to hear that - it sounds strange to me, that the X-T2 is not holding through a rain-shower... I know, it is not supposed to be submerged in water - but what weather the sealing is build for, if not rain? I used my X-T1 in hours of slight rain... even my "officially not sealed" Yongnuo 560 worked without problems... rain drops are exactly, what the sealing should prevent from entering the body.
An accidental splash of water imho is no "weather", but would be splash-proof (what e.g. my mobile is).
