Great drop to all atk(20%) = great boost to your element def(35).

Your defense and their attack will be calculated before the drop skills come into play.

Say you have a defense of 1 million. With a 25% boost, you can block 1.25 million. With a 20% drop, you can block the same amount, because 20% of 1.25 million is 250k. It's equal in power, but it isn't necessarily better unless your backline isn't completely your element. However - a great drop to element atk is(likely) a 25% drop. That is better than any boost you can get, but except for Heroes Colosseo, you can't set lines for each element. So if you have a great drop in fire atk, and a forest player attacks you, the card is useless.
