And that Ladies and Gentlemen is why we don't do dual type moves.
Although like with the dual types, I'd go with the prominent type with the dual moves.
Like say, Venusaur, it's a Grass/Poison, but the Grass traits stick out more, so hence my thoughts of it being Grass. Same here.
But yeah, some moves would be nice for a side effect/type. It works for the card game at times. I'm not saying a lot but a sparse sampling would be nice to test.
To get back on topic ish, Reflect should be more than a wall, it should be Counter given the connotations of the mirror effect.
