It's 10%, not 15%. Together with the Wyrmking's Ring it's ~20%. In the casting time video, some admittedly cursory timer-ogling shows that the cast bar finishes filling at 10s with neither boost active, and finishes around 8-8.2s with both boosts active.

Less scientifically, having both cast time boosts active just doesn't -feel- like a 30% reduction at all, before we even consider that it only speeds up the bar filling and not the actual cast animation.
