The additional effect of spells of the Light and Shadow schools deals more base damage, they are activated more quickly, but work with a reduced chance. The chances of triggering are now the same at all spell levels (for example, Streams of Light III previously applied "Painful Shock that causes 75 damage over 30 seconds", now a Painful Shock deals 105 damage over 25 seconds).
25% chance= 100 damage instead of 400 damage (because instead of 4 times, it just triggers once due to it's probability)
3 times the damage (being very optimistic)= 300 damage instead of 400 damage.
If it's a buff to you, then think about the meaning of a buff once again, try to use your skill in English language since maths obviously failed you here.

He said 25% less, not 25% compared to 100%. It wasn't 100% before...
