Basically saying that the treasures were changed to give the game more of a combat side,

before we were giving the resources freely for holding it with just one unit, now you have to defend to have this resource

The viewing of the source is better for you and those whom hold the treasure, 

scouting is always better for you...

To give HUGE rewards for taking out one bonnie seems to make attacking far more rewarding than foraging.

I send one buccaneer and one bonnie to an island  Often they are pounced on by forces that would frighten the Spanish Armada being escorted by the U.S. Navy,

These captains tell me, they get frigates and all manner of goodies for this daily attack

The only reward for "farming" is to make an arrangement with an attacking captain to be there to be taken and have some resources change hands.

UPDATE 15 may I have been approached by a captain to Attack him on a "set up" island so I can get MY frigates.   

Hardly inspiring game play
