Mikeal's Crucible active should be lowered to 120 second cooldown..
The fact that its still 180 seconds is astonishing it literally double or triples most items in the game, and it is the longest active item cooldown in the game. It has never really bounced completely back from when it used to cost 1600 gold which made it too strong early. This would help its mid to late game some. Even if it's cooldown becomes 120 seconds with masteries the cooldown is 96 seconds. That is if you take them which isn't ALWAYS the case. Even then if you lowered the cooldown to just 150 seconds with masteries the cooldown would be 120 seconds. A change like this would not make the item super op like when it was so cheap, and could be obtained basically as your first item. The game has changed so much since 2012 when the item was released this change just seems simple and logical to me.
