Of course in D/P 80 became the new standard, but it's not necessarily something we have to follow. Though Signal Beam is slightly more prevalent in Topaz, Silver Wind remains the standard Bug special move among other type disparities. I'd venture to say that Dolphure doesn't require a light-type move. Light fails to hit hard what resists Water (in particular Grass) and so even with a power boost to Light Wave Ice Beam would still be the superior option. Ice is just that good in canon games.
