I do think the Curse well should cost more, due to what it brings. To explain further, The well allows you the chance to gain a well for yourself and also make the enemy no long gain resources from that well permanently unless they re take it, this could allow you to bait a fight or more and also allow you to gain control of the well. On the other side the curse orb only disables the target well for 15 seconds and after that the enemy will gather resources once again and still have control over the well. Overall the well gives the ability for your self to gain a much greater advantage over the enemy and also allows strategic plays to be set up. The Curse well is defiantly very useful and the Curse orb i think is useless. That's my opinion
