It is an exploit. This card is meant to be used with aroma.
Konami made a mistake. The first sentence should be added 'while you control an aroma monster'. Otherwise this card will be too OP. Destroying enemy's everytime you gain LP? There are tonnes of way to gain LP!
There are lots of cards that are part of an archetype, but with generic effect that allows them to be used in other decks. It gives more value to the card, as it means you still can play the card even if you don't have the entire archetype.
Because once you flip Dried Winds face-up, each turn you'll always be forced to destroy first monster your opponent summons. Your opponent will be able to bait this effect easily leaving you defenseless for the rest of the turn. To use Dried Winds effectively you must be able to control when to trigger it.
"each turn you'll always be forced to destroy first monster your opponent summons"
I assumed that your opponent's field is empty, but the point still is that it will always trigger with the first summon each turn.
